TypeDefinition object

TypeDefinition is used in the VariableDefinition class.

Information about the type of a variable. The variable can be a single value, an object, or an array. TypeDefinition is an abstract class that is the ancestor of ClassDefinition, SimpleTypeDefinition, and EnumerationDefinition. It has no events.

Properties

TypeDefinition property	Datatype	Description
Category	TypeCategory	Specifies if the type is simple, enumerated, or a class or structure. Values are: SimpleType! EnumeratedType! ClassOrStructureType!
ClassDefinition	PowerObject	An object of type PowerObject containing information about the class definition of the object or control.
DataTypeOf	String	The system class name or simple datatype of the variable. DataTypeOf is a string representation of a value of the Object enumerated datatype. Values are lowercase with no exclamation point. Sample values include: window string any dropdownlistbox For objects you have defined, the datatype is the system class from which your object is inherited.
IsStructure	Boolean	Indicates whether the type is a structure.
IsSystemType	Boolean	Indicates whether the type is defined by PowerBuilder as opposed to a type defined in a PBL by a user.
IsVariableLength	Boolean	Specifies whether the datatype has a fixed size. Values are: TRUE – The datatype is variable length, meaning the datatype is a string, any, blob, or unbounded array. FALSE – The datatype is a fixed length.
IsVisualType	Boolean	Indicates whether the type is a visual (displayable) or nonvisual type. Values are: TRUE – The type is visual, for example, a window or a control. FALSE – The type is non-visual, for example, a class user object or a simple datatype.
LibraryName	String	The fully qualified name of the library the type was loaded from. Note that the library might no longer contain the type. If a program manipulates the contents of libraries, its class could have been moved or deleted after it was loaded.
Name	String	The name of the type. For a nested type, the name will be returned in the form of libraryEntryName`typeName
