Progress.Util.EnumHelper class

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

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

Add( ) method	And( ) method
AreEqual( ) method	AreNotEqual( ) method
Complement( ) method	IsGreater( ) method
IsGreaterOrEqual( ) method	IsLess( ) method
IsLessOrEqual( ) method	Or( ) method
Subtract( ) method	Xor( ) method

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

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)".

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)".

For information on the System.Enum class and .NET enumeration types, refer to the .NET Framework class library.
