Speicherleck bei der Verwendung von anonymen Methoden

[Stevie]

Antwort von Barry:

Zitat:

When you assign a regular method to a method reference it is actually identical to writing an anonymous method that wraps the method call:

Delphi-Quellcode:

TFooType = reference to procedure(fooArg: TFooArg);
foo: TFooType;

foo := Self.Bar;

foo := procedure(fooArg: TFooArg)
  begin
    Self.Bar(fooArg);
  end;

This captures 'Self' - so you could theoretically find out the instance to which the method reference is referring to, using RTTI tricks - but you would need to disassemble the code of the anonymous method to get to the method itself. If the method is virtual or dynamic, it will be using a different calling mechanism than if it is non-virtual, and similarly it will be more or less obscured.
