Member Function Documentation

template<class T> T* IT_Bus::Var< T >::get (   )  const throw (()) [inline]

Get the pointer but do not give up ownership. Do not reduce the reference count on the object. Returns: A pointer to the object. Definition at line 102 of file var.h. Referenced by IT_Bus::const_cast_var(), IT_Bus::dynamic_cast_var(), and IT_Bus::static_cast_var().

template<class T> T& IT_Bus::Var< T >::operator * (   )  const throw (()) [inline]

Dereferencing operator. Returns: A reference to the object. Definition at line 89 of file var.h.

template<class T> IT_Bus::Var< T >::operator T * (   )  const [inline]

Return the encapsulated T pointer. Returns: Pointer to T. Definition at line 176 of file var.h.

template<class T> T* IT_Bus::Var< T >::operator-> (   )  const throw (()) [inline]

Arrow operator. Returns: A pointer to the object. Definition at line 77 of file var.h.

template<class T> Var<T>& IT_Bus::Var< T >::operator= (  T *  ptr  )  throw (()) [inline]

Assignment operator. Parameters: A  pointer to the object. Returns: A reference to the Var. Definition at line 158 of file var.h.

template<class T> Var<T>& IT_Bus::Var< T >::operator= (  const Var< T > &  ptr  )  throw (()) [inline]

Assignment operator. Parameters: A  reference to a Var instance. Returns: A reference to the Var instance. Definition at line 132 of file var.h.

template<class T> T* IT_Bus::Var< T >::release (   )  throw (()) [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. Definition at line 117 of file var.h.
