You can get an instance of a Progress.Lang.Class containing the type information for a specified object type by invoking one of these two built-in ABL class methods:
GetClass( ) instance method of Progress.Lang.Object invoked on a valid object reference of the specified object type
GetClass( ) static method of Progress.Lang.Class invoked on that class type with the object type specified as a character parameter
As an alternative to the static GetClass( ), you can use the GET-CLASS function, which takes an object type name instead of an object type specified as a character string.
This is the syntax to get a Progress.Lang.Class instance containing the specified type information:
Element descriptions for this syntax diagram follow:
class-reference
A data element defined as a Progress.Lang.Class.
object-reference
A reference to an instantiated class-based object whose type information you want returned in the Progress.Lang.Class instance.
expression
A CHARACTER expression that evaluates to the fully qualified object type name of the type whose information you want returned in the Progress.Lang.Class instance.
For example, after the calls to GetClass( ) in the following procedure fragment, rType1 and rType2 each reference the same Progress.Lang.Class instance:
USING Progress.Lang.*.
USING acme.myObjs.*.
DEFINE VARIABLE rCustObj AS CLASS CustObj NO-UNDO.
DEFINE VARIABLE rType1 AS CLASS Class NO-UNDO.
DEFINE VARIABLE rType2 AS CLASS Class NO-UNDO.
