(Windows only; .NET)

A helper class that provides a set of static methods you can use to perform operations on .NET enumeration types in ABL.

Serializable:

No

Constructors

This class does not contain a constructor.

Super Class

This class does not inherit a super class.

Interfaces

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

Public Properties

This class does not contain properties.

Public Methods

Add( ) method (Progress.Util.EnumHelper) And( ) method
AreEqual( ) method AreNotEqual( ) method
Complement( ) method IsGreater( ) method
IsGreaterOrEqual( ) method IsLess( ) method
IsLessOrEqual( ) method Or( ) method
Subtract( ) method Xor( ) method

Public Events

This class does not contain events (beyond those it inherits from its base class).

Notes

  • The functionality for all of the methods of this class, except for Add( ) and Subtract( ), can be accomplished for .NET enums using ABL operators (e.g., you can use GE or >= operator instead of IsGreaterOrEqual( ), NOT operator (bitwise) instead of Complement( ), etc.). These methods are still supported for backward compatibility.
  • Some Progress.Util.EnumHelper methods return a System.Enum class instance. If you want to use the returned System.Enum instance as a different enumeration type, you must cast the instance to that specific type using the CAST function. For example:
    USING System.Windows.Forms.* FROM ASSEMBLY.
USING Progress.Util.* FROM ASSEMBLY.

DEFINE VARIABLE myButton AS Button.
DEFINE VARIABLE myStyle  AS System.Enum.

myButton = NEW Button().
myStyle  = EnumHelper:Or( AnchorStyles:Bottom, AnchorStyles:Right ).
myButton:Anchor = CAST( myStyle, AnchorStyles ).

/* Displays "Bottom, Right" */
DISPLAY STRING( myButton:Anchor ) FORMAT "x(20)".
