parameter GUIDENABLED = 1;
If this parameter is set to 1 then a GUID will be assigned (to the %GUID property) to each new object. When the object is saved for the first time this GUID value will be recorded in a namespace index which will allow GUID to be resolved to OIDs.
Default value of XMLREFERENCE that specifies how to project references to XML. XMLREFERENCE may be overridden for each property. SUMMARY indicates that only the summary properies of the referenced class are used to represent the reference. SUMMARY is the default. Note that by default all properties are of the referenced class are in the summary. COMPLETE indicates that all properties of the referenced class are used to represent the reference. ID indicates that the id of a persistent or serial class is used to represent the reference. OID indicates that the oid of a persistent or serial class is used to represent the reference. The form of the oid will be classname,id. GUID indicates the the GUID of a persistent class is used to represent the reference.


property GUID as %RawString (XMLPROJECTION = "ATTRIBUTE") [ Transient ];
Property methods: GUIDGet(), GUIDIsValid(), GUIDSet()


method GUIDGet() as %RawString [ Language = objectscript ]
method GUIDSet(Arg As %RawString) as %Status [ Language = objectscript ]
method XMLClear() [ Language = objectscript ]
Clear propety values in preparation for the values from XML import
classmethod XMLExchangeName(id As %String) as %String [ Language = objectscript ]
Returns an value to identify the object. This method may be overriden to return a code or description.
classmethod XMLExchangePath(id As %String) as %String [ Language = objectscript ]
For very large tables it is necessary to break the records down into sub-directories. This method returns the sub-directory name to be used for the given id.

The sub-directory returned is then appended to the path using ##class(%File).SubDirectoryName()

classmethod XMLGetElement(id As %String, Object As %RegisteredObject = $$$NULLOREF) as %String [ Language = objectscript ]
Return the Oid of the Exchange Item that contains this object.
classmethod XMLLoadGUID(document As %XML.Document, node As %Integer, containerOref As %RegisteredObject = "") as %RegisteredObject [ Language = objectscript ]
Returns a matching object based on unique indices
classmethod XMLNew(document As %XML.Document, node As %Integer, containerOref As %RegisteredObject = "") as %RegisteredObject [ Language = objectscript ]
Get an instance of an XML enabled class.

You may override this method to do custom processing (such as initializing the object instance) before returning an instance of this class. However, this method should not be called directly from user code.
document is the document with %XML.Node or macros in
nodeId is a node id of the node which defines this object. An %XML.Node object may be obtained for this node using document.GetNode(nodeId)
containerOref is the containing object instance when called from XMLImport and is "" when called from %XML.Reader for Correlate'd objects.
