overwrite

Summary

The overwrite modifier is used for method hiding/shadowing (early binding).

Syntax

overwrite member

Parameters

member: The member to attempt to overwrite.

Description

The overwrite keyword specifies a new implementation for a method inherited from a base class via early binding. It is also used for explicitly specifying the implementation for interface methods.

The overwrite keyword is used in contrast to override and final which specify late binding.
