Description

Frees an object reference and replaces the reference with nil (Delphi) or NULL (C++).

Use FDFreeAndNil to ensure that a variable is nil (Delphi) or NULL (C++) after you free the object it references. Pass any variable that represents an object as the AObj parameter. The behavior differs for ARC and non-ARC platforms:

• ARC--the method calls the DisposeOf method.
• non-ARC--the method calls the Destroy destructor.

Warning: AObj must be an instance of a TObject descendant.
