%SYSTEM.OBJ

abstract class %SYSTEM.OBJ extends %SYSTEM.Help

The %SYSTEM.OBJ class provides an interface for managing objects.

You can use it via the special $system object:

  Do $system.OBJ.Load("MyFile.xml","ck")
  

Many methods in this class use the qspec argument, which is a list of flags or qualifiers. See System Flags and Qualifiers.

Methods

deprecated classmethod CloseObjects() as %Status
Deprecated function, to close objects let them go out of scope.
classmethod Compile(ByRef classes As %String = "", qspec As %String = "", ByRef errorlog As %String, recurse As %Boolean = 0) as %Status
Compile a class.

Compiles the class classes, which can be a single class, a comma separated list, a subscripted array of class names. You can also use ? or * wild cards and if you wish to exclude items pass ' before the item name which also supports wild card, e.g. "User.*,'User.T*". If recurse is true then do not output the intial 'compiling' message or the compile report as this is being called inside another compile loop.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

classmethod CompileAll(qspec As %String = "", ByRef errorlog As %String) as %Status
Compile all classes within this namespace. By default it will not compile classes mapped from another database unless the qualifier '/mapped=1' is provided.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.
classmethod CompileAllNamespaces(qspec As %String = "", ByRef errorlog As %String) as %Status
Invoke $system.OBJ.CompileAll for all the namespaces.

Parameters

NameDescription
qspec

qspec is a list of flags and qualifiers that can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

errorlog

errorlog is an array of the %Status error values encountered during the execution of this method. Each status value is in the format returned by $system.Status.DecomposeStatus.

The return value is a %Status value indicating success or failure.

classmethod CompileInfoClass(class As %String, Output version As %String, Output compiletime As %String) as %Status
Given a class this returns the version of InterSystems IRIS this was compiled on and the compiletime of this class.
classmethod CompileInfoClose(QHandle As %Binary) as %Status
classmethod CompileInfoExecute(ByRef QHandle As %Binary, sortorder As %Integer = 0) as %Status
classmethod CompileInfoFetch(ByRef QHandle As %Binary, ByRef Row As %List, ByRef AtEnd As %Integer = 0) as %Status
classmethod CompileInfoFetchRows(ByRef QHandle As %Binary, FetchCount As %Integer = 0, ByRef RowSet As %List, ByRef ReturnCount As %Integer, ByRef AtEnd As %Integer) as %Status
classmethod CompileList(ByRef list As %String = "", qspec As %String = "", ByRef errorlog As %String, ByRef updatedlist As %String) as %Status
Compile a list of items specified in 'list' and separated by commas, or an array list("item.MAC")="". You can also use ? or * wild cards and if you wish to exclude items pass ' before the item name which also supports wild card, e.g. "User.*.cls,'User.T*.cls". Each item on the list is sufixed by the type of item it is so to compile a class and a routine you could specify 'class.cls,routine.mac' The order of compilation is INT, CLS, MAC, CSR, CSP.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'. Note that while /mapped=0 qualifier applies to the pattern passed in by only searching the default routine database, however any compile is done in the current namespace. So it is possible a routine/class found with /mapped=0 may not be visible in the current namespace or may be a different version if there are complicated package mappings.

classmethod GetPackageList(ByRef items As %String, package As %String, qspec As %String = "") as %Status
Return an array of classes in this package.

Search for classes in the package and put their names into the local array items. If the package is "*" then it will return for all classes in this namespace. It uses the qualfier in qspec /includesubpackages to determine if it searches inside a package to subpackages or not. qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

classmethod GetQualifiers(system As %Boolean = 0) as %String
Get the default qualifiers for this namespace or this system. If system is true, the method gets the default qualifiers for this system; otherwise it gets the default qualifiers for the current namespace.
classmethod GetTransactionMode() as %Integer
Return the current Object transaction mode.
classmethod ImportDir(dir As %String = "", wildcards As %String, qspec As %String = "", ByRef errorlog As %String, recurse As %Boolean = 0, ByRef imported As %String, listonly As %Boolean, ByRef selectedlist As %String)
Import and optionally compile all items in a directory.

This will import all files found in a directory using the Load() method so it should be able to detect most common formats. If you pass it the compile flag ('c'), after loading it will also compile all these items. The other flags are the same as found in Load() except for the dir which is the directory to load and the recurse which determines if this will look into subdirectories or not.
You can limit the items it will import by specifying a wildcards value. For example '*.xml' will only import files that end in XML.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

classmethod IsUpToDate(class As %String, log As %Boolean = 0, type As %Integer = 1) as %Boolean
For classes in a read/write database, return 1 if this class is up to date (or 0 if it is not). If log is true then it will display a log of what it is checking. The type determines *what* it checks to make the determination:
  • 0 - Check timestamps on class, so even if a description was modified this will show the class as out of date
  • 1 - Ignore changes to descriptions in checking up to date status, this is the default and is what the class compiler typically uses.
  • 2 - Ignore changes to descriptions and method code in checking up to date status, this is useful to see if the class has 'structurally' changed in a way that would require a class referencing this via SQL to be recompiled
This method returns 1 if the class is in a read-only database.
classmethod IsValidClassname(class As %String) as %Status
Return $$OK if this class name is valid, or an error message if it is not. If it is invalid it is typically because it contains characters that are not allowed in a class name or because it clashes with a class that already exists (different case in package say).
classmethod Load(file As %String = "", qspec As %String = "", ByRef errorlog As %String, ByRef loadedlist As %String, listonly As %Boolean, selecteditems As %String, displayname As %String, charset As %String = "", ByRef description As %String) as %Status
Load a file from disk.

Load, and optionally compile (if 'c' flag is present), class definitions, CSP pages, routines, or globals from the file file. file may be a list of files to load separated with '*' symbols.
You can import files exported in XML format, %RO format, CDL format, UDL format, %GOF, and CSR/CSP files.
A comma separated list of the items it loaded is returned in loadedlist. If the list is too long to fit in the variable, it is terminated with '...'. Items loaded are always returned as subscripts of the loadedlist array.
If you pass listonly as true then it will not import anything but just list the items that exist in file.
If selecteditems is defined then this will contain either a comma separated list of items to import or a single subscripted array. It will only import items that are in this list from the file provided, so this provides a way to limit which items get imported.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.
When loading a %RO file the description variable will be filled in with the description from the %RO file if there is one present.
errorlog is an array of the %Status return values from this call, in the format returned by $system.Status.DecomposeStatus.
The displayname is normally not provided. If present it changes the 'load file XYZ' name from the filename to the displayname. This is useful when loading a stream where the stream filename is not the name of the file the user knows from a client system and we want to present a meaningful name.
If the filename ends in .gzip or .gz then we ungzip this file before loading it.

classmethod LoadDir(dir As %String = "", qspec As %String = "", ByRef errorlog As %String, recurse As %Boolean, ByRef loadedlist As %String) as %Status
Load all class definitions in a directory.

Load and optionally compile (if 'c' flag is present) all class definitions within directory dir, this includes all .XML files. If the recurse is true then it will include subdirectories. Returns a comma separated list of the items it loaded in loadedlist and the same data also as loadedlist(name)="" in case the comma list is more than 32k. Note that this will only compile classes found in these XML files and no other types. If you want to be able to compile anything use the ImportDir().
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

classmethod LoadLanguage(language As %String = "", qspec As %String = "") as %Status
Import the system messages for the specified language from ...\mgr\Locale\allmessages_[language].xml and make this the current language. If language is not specified, then Upgrade the Object locale and import the current language.
classmethod LoadStream(stream As %AbstractStream, qspec As %String = "", ByRef errorlog As %String, ByRef loadedlist As %String, listonly As %Boolean, selecteditems As %String, displayname As %String, charset As %String = "") as %Status
Load a stream.

Load and, optionally compile (if 'c' flag is present), class definitions, CSP pages, routines or globals from the stream stream. Returns an array of the items it loaded in loadedlist. If you pass listonly as true then it will not import anything but just list the items that exist in the stream that you supply.
If selecteditems is defined then this will contain a comma separated list of items to import (or a single subscripted array). It will only import items that are in this list from the stream provided, so this provides a way to limit which items get imported.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.

classmethod MakeClassDeployed(ByRef classes As %String = "", qspec As %String = "", fulldeploy As %Boolean = 0) as %Status
Make a class or classes deployed. classes can be a single class, a comma separated list, a subscripted array of class names. You can also use ? or * wild cards and if you wish to exclude items pass ' before the item name which also supports wild card, e.g. "User.*,'User.T*". This will delete all the source code of the class from the disk. Once a class is in deployed mode, it can not be edited or exported or recompiled. You can still create subclasses of a deployed class and compile these. qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'. If fulldeploy is true it will attempt to remove pretty much the entire class definition leaving just the minimum so the class is runnable, this will not work on persistent, serial, datatype, or XML enabled classes as these require access to the class definition at runtime in order to function. Note that for a class to be deployed it must be compiled, if you try to deploy a class which is not compiled it will report an error.
classmethod New(ClassName As %String = "") as %ObjectHandle
Create a new object instance.

Create a new object instance of type ClassName and return a reference (OREF) to it.

Using this method, you can dynamically create objects, that is you can determine what type of object to create at run-time.

For example:

  Set obj = $System.OBJ.New("Person")
  
classmethod ObjectListClose(QHandle As %Binary) as %Status
classmethod ObjectListExecute(ByRef QHandle As %Binary) as %Status
classmethod ObjectListFetch(ByRef QHandle As %Binary, ByRef Row As %List, ByRef AtEnd As %Integer = 0) as %Status
classmethod Open(ClassName As %String = "", oid As %String = "") as %ObjectHandle
Open a persistent object instance.

Load persistent object instance of type ClassName and with OID value oid from disk and return a reference (OREF) to it.

For example:

  Set person = $System.OBJ.Open("Person",oid)
  
classmethod OpenId(ClassName As %String = "", id As %String = "") as %ObjectHandle
Open a persistent object instance.

Load persistent object instance of type ClassName and with ID value id from disk and return a reference (OREF) to it.

For example:

  Set person = $System.OBJ.OpenId("Person",22)
  
classmethod RebuildExtentIndex(updateMode As %Boolean = 0, lockMode As %Integer = 1) as %Status

The Extent Index is an index on all persistent classes that are runnable in the current namespace. It is currently used by %BuildIndices, %KillExtent, and the %FindGUID utility function in %Library.GUID. Other uses may be added at a later time.

The index is maintained in the globals database in the current namespace. If the globals database in the current namespace is readonly then an error will be returned. The class compiler automatically maintains this index for classes compiled in the namespace. Classes mapped from other namespaces are not automatically added to or removed from the index when mapping changes or changes to the class runtime occur in the original namespace. Such changes must be updated in the local namespace's extent index by running a utility function. There are two functions, this function will rebuild the index completely and RebuildExtentIndexOne() will rebuild the index entries for only the specified class.

This function returns a status value indicating success or failure.

Parameters

NameDescription
updateMode

If zero then the extent index is purged and rebuilt completely. Otherwise, the existing index is checked against existing defintions and only changed classes are rebuilt.

lockMode

Specifies the type of locking to be used while modifying the index. If the requested locks cannot be obtained then an error is reported to the caller.

0No locking;
1Exclusive lock on the entire extent index, released immediately on completion;
2The nodes for each class in the extent index are locked during update, released immediately when class's index entries are built;
3Shared lock on the entire extent index, released immediately on completion.

The return value is a %Status value indicating success or failure.

classmethod RebuildExtentIndexOne(className, lockMode As %Integer = 1) as %Status

This function updates the extent index for the specified class in the current namespace. If the globals database in the current namespace is readonly then an error will be returned. Call this function to rebuild the extent index for a single class in the current namespace. Refer to RebuildExtentIndex() for more information.

This function returns a status value indicating success or failure.

Parameters

NameDescription
className

The name of the class to be indexed.

lockMode

Specifies the type of locking to be used. If the requested locks cannot be obtained then an error is reported to the caller.

0No locking;
1The nodes for each class in the extent index are locked during update, released immediately when class's index entries are built;
2The nodes for each class in the extent index are locked during update, released immediately when class's index entries are built;
3Shared lock on the class nodes in the extent index, released immediately on completion.

The return value is a %Status value indicating success or failure.

classmethod RedirectBindSrvUserOutput(val As %Boolean)
Turn output redirection on and off in the binding server.
classmethod SaveObjects() as %Status
Save all instances of %Library.Persistent in the process. Returns a status value.
classmethod SetConcurrencyMode(value As %Integer = 1, ByRef pStatus As %Library.Status) as %Integer
Set the Object concurrency mode for the current process to a new value. Valid values are:

0No concurrency controls
1Atomic
2Shared
3Shared retained
4Exclusive
If a valid value is passed in then the concurrency mode for the current process will be set to that value and the previous concurrency mode value is returned. Otherwise the concurrency mode setting is left unchanged and pStatus will contain a %Status value describing the error and the current concurrency mode value is returned.
classmethod SetFlags(flags As %String, system As %Boolean = 0) as %String
Set the default flags for this namespace or this system. If system is true then this sets the default flags for this system, otherwise it sets the default flags for this namespace. If flags are set for this namespace these override any set for the system. These flags are combined with the built in defaults to create the defaults used. This method returns the new defaults after this change.
classmethod SetMPPOption(optionName As %String = "", optionValue As %Integer = "", ByRef oldValue As %String) as %Status
Set the specified Macro Pre-Processor (MPP) Configuration Settings 'optionName' to the specified 'optionValue'

------------------------------------------------------------------------------- Method: SetMPPOption Definition: This method sets the specified Macro Pre-Processor (MPP) Configuration Settings 'optionName' to the specified 'optionValue'.

classmethod SetQualifiers(qspec As %String = "", system As %Boolean = 0, group As %String) as %Status
Set the default qualifiers for this namespace or this system. If system is true then this sets the default qualifiers for this system, otherwise it sets the default qualifiers for this namespace. If qualifiers are set for this namespace these override any set for the system. These qualifiers are combined with the built in defaults to create the defaults used. The argument group has been deprecated.
classmethod SetTransactionMode(value As %Integer = 1, ByRef pStatus As %Library.Status) as %Integer
Set the object transaction mode for the current process to a new value. Valid values are:

0No transactions used for Object filing
1Use transactions for Object filing
If a valid value is passed in then the transaction mode for the current process will be set to that value and the previous transaction mode value is returned. Otherwise the transaction mode setting is left unchanged and pStatus will contain a %Status value describing the error and the current transaction mode value is returned.
classmethod ShowClasses(qspec As %String = "") as %Status
Write all classes defined in this namespace to the console.

The optional qspec argument is a qualifier string containing any of the following options:

/detailShow details.
/hiddenShow hidden classes.
/mappedShow mapped classes.

For example:

  Do $System.OBJ.ShowClasses("/detail")
  
classmethod ShowFlags()
Display the list of flags used by the compiler. Should use ShowQualifiers() as flags have been superseded by qualifiers.
classmethod ShowMacros()
Display the list of supported macros defined in the system.
classmethod ShowObjects(qspec As %String = "") as %Status
Write all object instances in this process to the console. Note that some of the objects displayed may be process specific singleton objects such as classes in the %SYSTEM.Context package or oref's these singleton objects themselves hold.

The optional qspec argument is a string containing any of the following characters:

/detail=1Show details.

For example:

  Do $System.OBJ.ShowObjects("/detail=1")
  
classmethod ShowQualifiers(group As %String = "")
Display the list of qualifiers defined in the system. It also shows the default qualifiers defined at system level and at namespace levels. The argument group has been deprecated.
classmethod ShowReferences(oref As %String, chkObj As %Boolean = 0)
Display a list of all variables that contain a reference to this oref. If chkObj is set to 1, the properties of any varibles that contain an object reference will also be searched and displayed. Otherwise only non-object variables will be searched.
The list has the base $STACK level of the variable, the internal stack level (as shown by the %STACK utility), and the variable name.
classmethod UnCompile(ByRef classes As %String = "", qspec As %String = "") as %Status
Uncompile a class or classes. classes can be a single class, a comma separated list, a subscripted array of class names. You can also use ? or * wild cards and if you wish to exclude items pass ' before the item name which also supports wild card, e.g. "User.*,'User.T*". qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'.
classmethod UpdateConfigParam(classname As %String, parameter As %String, value As %String) as %Status
Allows updating a CONFIGVALUE parameter type. If you have defined a parameter in the classname which is specified as 'CONFIGVALUE' in the type keyword then this function allows this to be updated from the original value to a new value. Note that this should be a rare event and not be used for any value that needs to be updated a lot, a global should be used for a rapidly updating value. The advantage of using a class parameter for a configuration value is that a very large number of processes can access this value using 'Set val=##class(ClassName).#ParamName' faster than access to a global.
classmethod Upgrade(qspec As %String = "", ByRef errorlog As %String, classname As %String) as %Status
Upgrade the class definition database in one namespace. Pass in qspec /mapped=1 to upgrade databases mapped into current namespace or if you pass in classname we will upgrade the database associated with this specific class.
classmethod UpgradeAll(qspec As %String = "", ByRef errorlog As %String) as %Status
Upgrade the class definition database in all the namespaces. Pass in qspec /mapped=1 to upgrade databases mapped into current namespace
classmethod ValidateIndices(classname As %Library.String, idxList As %String = "", autoCorrect As %Boolean = 0, lockOption As %Integer = 1, multiProcess As %Boolean = 0, verbose As %Boolean = 1, ByRef errors As %String) as %Library.Status
Validate indices for a class

Parameters:
classname
Name of the persistent class to validate indices for.
idxList
Optional. "" to check all indices, or specify a $list of index names to check. Default=""
autoCorrect
Optional. If true, correct any errors found. Default=0
lockOption
Optional. Default = 1 0 - No locking is performed at all 1 - Shared locking as each row is checked 2 - exclusive lock on entire table for duration of the run
multiProcess
Optional. If true, parts of %ValidateIndices will use parallel processing when possible. Default=0
verbose
Optional. If true, display output to the current device. Default=1. When called for a sharded class, verbose is force to 0.
errors
Optional. Passed by reference. Returns an array of errors found in the index(es) validated. If autoCorrect=1, this is an array of issues corrected.

Returns:

Status Code

Example:

  • Do $SYSTEM.OBJ.ValidateIndices("Sample.Person","",1,2)
  • Do $SYSTEM.OBJ.ValidateIndices("Sample.Company",$lb("NameIdx"),1,1)
  • Note::
    Indices may also be validated by calling the class method ##class(classname).%ValidateIndices(idxList,autoCorrect,lockOption,verbose).
    There is one main difference between validating indices through $SYSTEM.OBJ.ValidateIndices() and ##class(classname).%ValidateIndices().
    $SYSTEM.OBJ.ValidateIndices() will validate the indices for a table, and it will also validate any indices in collection child tables for that table.
    When using ##class(classname).%ValidateIndices(), collection child table indices must be checked with separate calls.
    Also, when calling $SYSTEM.OBJ.ValidateIndices(), multiProcess default is 0. When calling ##class(classname).%ValidateIndices(), multiProcess default is 1.

    classmethod Version() as %String
    Return the version number of the current object library.

    Queries

    query CompileInfo(sortorder As %Integer = 0)
    Selects Name As %String, Version As %String, Time As %TimeStamp
    Query to return version and time when classes were compiled. This only returns compiled classes, so classes not compiled are skipped. The sortorder can be one of:
    • 0 - Time class was compiled (default)
    • 1 - Classname
    • 2 - InterSystems IRIS version
    query ObjectList()
    Selects OREF As %Integer, ClassName As %String
    This query returns a list of all object instances currently in memory within the current process.
