Methods​

%GenerateCode​

Method %GenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) As %Status [ Final, Internal ]

Generate code for this node.
User classes should not override this method, instead they should override the %OnGenerateCode method.

%OnGenerateCode​

Method %OnGenerateCode(pTargetClass As %Dictionary.CompiledClass, pCode As %Stream.TmpCharacter, pDocument As %XGEN.AbstractDocument) As %Status

Generate code for this node.
This method is called when a class containing an XGEN document is compiled.
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 will provide an implementation of this method that will generate specific lines of code.
For example: Do pCode.WriteLine(..%Indent()_"Set " _ ..target _ "=" _ $$$quote(..value))
