FOR EACH x OF Syntax_description.Parameter
Trace(x.Name)
END

Syntax

<Result> = GetTypeDefinition(<Element name>)

<Result>: Definition

Definition variable.

<Element name>: Character string

Name of the class or structure for which the definition should be retrieved.
New in version 28
Name of the window, page or report for which the definition should 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.

Limitations

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.
