Stored procedures
Retrieves the description of a type identified by its name.
Example
PROCEDURE Proc(ClassName is string)
 
// Retrieves the definition of the class identified by its name
MyDefinition is Definition
MyDefinition = GetTypeDefinition(ClassName)
Syntax
<Result> = GetTypeDefinition(<Name of Class or Structure>)
<Result>: Definition
Definition variable.
<Name of Class or Structure>: Character string
Name of the class or structure for which the definition must be retrieved.
Remarks

Retrieving the definition

If the class or structure is unknown, GetTypeDefinition returns a Null definition with a non-fatal error ("Invalid definition").
If the element is not allocated, GetTypeDefinition returns a Null definition with a non-fatal error ("Element not allocated").
The error cases can be processed:
  • by comparing the description to Null.
  • by checking the value of the ErrorOccurred variable.

Limits

  • In a project, you cannot retrieve the definition of a class or structure coming from:
    • an external component.
    • an internal component.
  • In an external component, you cannot retrieve the definition of a class or structure coming from the host project.
Component: wd270vm.dll
