TObject.Free

Check for Nil and call destructor.

Declaration

Source position: objpash.inc line 194

public procedure TObject.Free;

Description

Free will check the Self pointer and calls Destroy if it is different from Nil. This is a safer method than calling Destroy directly. If a reference to the object must be reset as well (a recommended technque), then the function FreeAndNil should be called.

Errors

None.
