If XMLIGNORENULL is set = 1, then both missing tags in the XML and empty strings are input as "", and both "" and $c(0) are output as empty tags (i.e. <tag></tag>).
If XMLIGNORENULL is set = "inputonly", then both missing tags in the XML and empty strings are input as "". Output of "" and $c(0) are for XMLIGNORENULL = 0: $c(0) is output as an empty tag (i.e. <tag></tag>) and "" is output as no tag.
If XMLIGNORENULL = "runtime" (runtime is not case sensitive), then the behavior of XMLIGNORENULL is determined by the format parameter of XMLExport, XMLImport and %XML.Reader.OpenFile. The default behavior for XMLIGNORENULL="runtime is the same as XMLIGNORENULL=0. Adding "ignorenull" to the format argument changes the behavior to that of XMLIGNORENULL=1. "ignorenull" shoud be separated by a comma from literal/encoded part of the format. Example values for format are "", ",ignorenull", "literal,ignorenull" and "encoded,ignorenull". Note that "inputonly" is equivalent to using ,ignorenull for XMLExport and not for %XML.Reader.
Methods (Including Private)
This method adds the current object to the SaveSet containing objects that are part of the current %Save() for persistent classes or %GetSwizzleObject for serial classes. A queue of objects to be saved or serialized is also constructed. Only modified objects are included in the save queue. The value (OID or serial value in OID form) of each object is also placed in the SaveSet.
This method will invoke the %OnAddToSaveSet method if it is implemented. See that method for more information.
%AddToSaveSet should not ever be invoked directly except from %OnAddToSaveSet().
This method takes these parameters:
depth, with these values:
|1:||Include this object in the SaveSet and, if it has not been serialized put it in the save queue and invoke %AddToSaveSet on any objects referenced by this object to the SaveSet with a depth of 1.|
|2:||Include this object in the SaveSet and save queue. Also invoke %AddToSaveSet on any referenced objects in the SaveSet with a depth of 1.|
|3:||Include this object in the SaveSet and, if modified, the save queue. Also invoke %AddToSaveSet on any referenced objects in the SaveSet with a depth of 3.|
|0:||Add this object to the save set only if it isn't already included.|
|1:||Add this object to the SaveSet even if it already exists. This causes object dependencies to be rebuilt. Typically, this value is only passed by %OnAddToSaveSet when it modifies objects other than the current one.|
Note: Swizzled serial objects always have an empty serial value and will always be placed in the save queue and the SaveSet. the value of depth simply gets passed on to its referenced objects.
Note that even if deep=0 when you clone a parent object in a parent child relationship or a one object of a one to many relationship then it will construct clones of all the child/many objects. This is because a child/many object can only point at a single parent and so if we did not create a clone of these then you would have a relationship with zero items in it. If you really just want to clone the object without these child/many objects then pass deep=-1 to this method.
After the clone is constructed it will call %OnConstructClone(object,deep,.cloned) on the clone if it is defined so that you can perform any additional steps e.g. taking out a lock. This works just the same way as %OnNew() does.
The object is the oref of the original object that was cloned. The cloned array is just used internally when doing a deep clone to prevent recursive loops, do not pass anything in at all for this parameter on the initial call. If you write a %OnConstructClone and from here you wish to call %ConstructClone on another object pass in the cloned array, e.g. 'Do oref.%ConstructClone(1,.cloned)' so that it can prevent recursive loops.
The location is used internally to pass the new location for stream objects.
If value starts and ends with #( )#, then return an expression
This method removes the current object from the SaveSet. If this object is also in the save queue it is removed from there as well.
%ValidateObject() does the following:
- It tests if any required property values are missing.
- If the PROPERTYVALIDATION class parameter is set to ValidateOnSave, it validates each non-null property value by calling the property method IsValid on each literal property and the object's %ValidateObject method for object-valued properties.
- If present, it will call a user-supplied %OnValidateObject() method.
If any of these tests fail, %ValidateObject() immediately returns an error value. It is up to the caller of %ValidateObject to process the error value.unused is not used. checkserial will force the checking of any serial properties by calling their %ValidateObject methods after swizzling this property.
Returns a %Status value indicating success or failure.
top is the optional tag to be used for the top-level tag.
format is the parameter formatting type. DTDs may only be generated for the default "literal" format.
input=true means that the DTD for the input XML will be generated, otherwise the DTD for the output XML will be generated. The default is input=false. Normally, this argument is not relevant since the all properties of a class participate in input and output.
The dtdlist argument is used internally to track DTD generation for referenced objects.
