%XGEN.AbstractGroup

abstract class %XGEN.AbstractGroup

Note: This class is included because it is needed by other parts of the library. You should not use this or any other class within this package within your applications as a future version will be incompatible. If you are interested in this functionality please contact InterSystems.

This abstract class is the basis for all groups within XGEN (such as documents or sequences).
See %XGEN.AbstractDocument for an overview of XGEN.
User classes should not extend this class, instead they should extend either %XGEN.AbstractDocument or %XGEN.AbstractSequence.

Properties

property children as list of AbstractNode (XMLELEMENTREF = 1, XMLPROJECTION = "ELEMENT", XMLTYPECONSTRAINT = "CHOICE");
This is the set of child nodes that belong to this sequence.
Property methods: childrenBuildValueArray(), childrenCollectionToDisplay(), childrenCollectionToOdbc(), childrenDisplayToCollection(), childrenGet(), childrenGetObject(), childrenGetObjectId(), childrenGetSwizzled(), childrenIsValid(), childrenOdbcToCollection(), childrenSet(), childrenSetObject(), childrenSetObjectId()
property skipChildren as %Boolean (XMLPROJECTION = "NONE") [ InitialExpression = 0 ];
If this transient property is true, then the children of the group will not be processed. This provides a way for a subclass to disable processing of a group.
Property methods: skipChildrenDisplayToLogical(), skipChildrenGet(), skipChildrenIsValid(), skipChildrenLogicalToDisplay(), skipChildrenNormalize(), skipChildrenSet()

Methods

final method %GenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) as %Status
Loop over the members of this sequence and fire their %GenerateCode() methods.
Subclasses can customize the behavior using the %OnBeforeGenerateCode() and %OnAfterGenerateCode() callback methods.
method %OnAfterGenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) as %Status
This method is called when a class containing an XGEN document is compiled. It is called after the %GenerateCode() method processes its children.
pTargetClass is the class that contains the XGEN document.
pCode is a stream containing the generated code.
pDocument is the top-level XGEN document object that contains this node.
A subclass can provide an implementation of this method that will generate specific lines of code.
method %OnBeforeGenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) as %Status
This method is called when a class containing an XGEN document is compiled. It is called before the %GenerateCode() method processes its children.
pTargetClass is the class that contains the XGEN document.
pCode is a stream containing the generated code.
pDocument is the top-level XGEN document object that contains this node.
A subclass can provide an implementation of this method that will generate specific lines of code.
final method %OnGenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) as %Status
This callback does not apply to groups, so we stub it out here.
