Member Function Documentation

template<class T>

void PointerTo< T >::clear ( ) [inline]

A convenient way to set the PointerTo object to NULL.

(Assignment to a NULL pointer also works, of course.)

Reimplemented from PointerToBase< T >.

Definition at line 117 of file pointerTo.h.

template<class T>

bool PointerTo< T >::is_null ( ) const [inline]

Returns true if the PointerTo is a NULL pointer, false otherwise.

(Direct comparison to a NULL pointer also works.)

Reimplemented from PointerToVoid.

Definition at line 116 of file pointerTo.h.

template<class T >

PointerTo< T >::operator T * ( ) const [inline]

We also have the typecast operator to automatically convert PointerTo's to the required kind of actual pointer.

This introduces ambiguities which the compiler will resolve one way or the other, but we don't care which way it goes because either will be correct.

Definition at line 82 of file pointerTo.I.

template<class T >

PointerTo< T >::To * PointerTo< T >::p ( ) const [inline]

Returns an ordinary pointer instead of a PointerTo.

Useful to work around compiler problems, particularly for implicit upcasts.
