A WeakConstPointerTo is similar to a WeakPointerTo, except it keeps a const pointer to the thing, that will be cleared to NULL when the thing deleted. More...

A convenient way to set the PointerTo object to NULL. | |
const To * | get_orig () const |
Returns the original pointer value, even if the object has since been deleted. | |
bool | is_null () const |
Returns true if the PointerTo is a NULL pointer, false otherwise. | |

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

void WeakConstPointerTo< T >::clear | ( | ) | [inline] |
A convenient way to set the PointerTo object to NULL.
(Assignment to a NULL pointer also works, of course.)
Reimplemented from WeakPointerToBase< T >.
Definition at line 99 of file weakPointerTo.h.
const WeakConstPointerTo< T >::To * WeakConstPointerTo< T >::get_orig | ( | ) | const [inline] |
Returns the original pointer value, even if the object has since been deleted.
Definition at line 277 of file weakPointerTo.I.
bool WeakConstPointerTo< 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 98 of file weakPointerTo.h.
WeakConstPointerTo< T >::operator const T * | ( | ) | const [inline] |
We also have the typecast operator to automatically convert WeakConstPointerTo'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 250 of file weakPointerTo.I.
const WeakConstPointerTo< T >::To * WeakConstPointerTo< T >::p | ( | ) | const [inline] |
Returns an ordinary pointer instead of a WeakConstPointerTo.
Useful to work around compiler problems, particularly for implicit upcasts.
