FindClassDefinition

Description

Searches for an object in one or more PowerBuilder libraries (PBLs) and provides information about its class definition.

Syntax

FindClassDefinition ( classname {, librarylist } )

Argument

Description

classname

The name of an object (also called a class or class definition) for which you want information.

librarylist (optional)

An array of strings whose values are the fully qualified pathnames of PBLs. If you omit librarylist, FindClassDefinition searches the library list associated with the running application.


Return value

ClassDefinition. Returns an object reference with information about the definition of classname. If any arguments are null, FindClassDefinition returns null.

Usage

There are two ways to get a ClassDefinition object containing class definition information:

  • For an instantiated object in your application, use its ClassDefinition property

  • For an object stored in a PBL, call FindClassDefinition

Examples

This example searches the libraries for the running application to find the class definition for w_genapp_frame:

ClassDefinition cd_windef
cd_windef = FindClassDefinition("w_genapp_frame")

This example searches the libraries in the array ls_libraries to find the class definition for w_genapp_frame:

ClassDefinition cd_windef
string ls_libraries[ ]
 
ls_libraries[1] = "c:\pwrs\bizapp\windows.pbl"
ls_libraries[2] = "c:\pwrs\framewk\windows.pbl"
ls_libraries[3] = "c:\pwrs\framewk\ancestor.pbl"
 
cd_windef = FindClassDefinition(
      "w_genapp_frame", ls_libraries)
