Progress.Lang.Class class

Progress.Lang.Class provides type information about an ABL class or an interface. ABL provides a Progress.Lang.Class instance for each ABL class or interface type in the ABL session.

Constructors

This class contains only a private constructor; you cannot instantiate it directly.

Super Class

Progress.Lang.Object class

Interfaces

This class does not implement interfaces (beyond those it inherits from its base class).

Notes

ABL does not support this class for use with .NET object types.
To obtain the object reference for the Progress.Lang.Class instance associated with a given ABL class or interface, you must call the GetClass( ) method either as an instance method on an ABL class (any Progress.Lang.Object instance except a .NET type) or as a static method of Progress.Lang.Class using the following syntax:

Syntax

class-reference = object-reference:GetClass( ). class-reference = Progress.Lang.Class:GetClass( expression ).

Where object-reference is the object reference to an ABL class instance for which you want to get the type information, expression is a CHARACTER expression that specifies the fully-qualified ABL object type name whose type information you want to get, and class-reference is the object reference for the Progress.Lang.Class instance containing that type information. For example:

DEFINE VARIABLE myCustObj AS Progress.Lang.Object NO-UNDO. DEFINE VARIABLE myType    AS Progress.Lang.Class  NO-UNDO. ASSIGN   myType    = Progress.Lang.Class:GetClass("acme.myObjs.CustObj")   myCustObj = myType:New( ).

Progress.Lang.Class is FINAL and cannot be inherited by another class. You cannot explicitly delete a Progress.Lang.Class instance.
