Summary

Frees an object reference and replaces it with nil.

Parameters

Parameters	Description
Obj	Reference to an instance of a TObject descendant to free. Upon return the Obj variable has been reset to nil so future references ensure a relatively easy to understand access violation.

Description

FreeAndNil frees the object instance pointed to by Obj and replaces the reference with nil. This ensures that the reference is nil after the object has been destroyed and helps debugging. Do not use this routine on objects or generic pointers which are not TObject descendants. For generic pointers you can use the FreeMemAndNil procedure.
