template<class T>

T* IT_Bus::Var< T >::release

(

)

[inline]

Release the reference, giving up responsibility for calling _remove_ref to the caller.

Set internal pointer to 0 since it no longer points to a valid reference; do not reduce the reference count on the object.

Returns:

A pointer to the object.
