TXMLDocument._AddRef Method

Called when an application uses a component interface.

Pascal

function _AddRef: Integer; stdcall;

C++

__fastcall __stdcall int _AddRef();

Description

__AddRef is a basic implementation of the IInterface method, _AddRef.

Note: If the component is a wrapper for a COM object, __AddRef calls the _AddRef method of that COM object, and returns the resulting reference count.

In all other cases, __AddRef simply returns –1 and takes no action. This allows the component to implement interfaces where reference counting is not required. More sophisticated components should override __AddRef to implement reference counting.
