This works exactly like PointerTo, except that the object is designed to be thread-safe: it is generally safe to make unprotected assignments to this pointer, in the sense that the last assignment will win and the reference counts will be properly maintained. More...

ThreadSafePointerTo (To *ptr=(To *) NULL) | |
ThreadSafePointerTo (const ThreadSafePointerTo< T > ©) | |
void | clear () |
A convenient way to set the ThreadSafePointerTo object to NULL. | |
bool | is_null () const |
Returns true if the PointerTo is a NULL pointer, false otherwise. | |
operator T * () const | |
We also have the typecast operator to automatically convert ThreadSafePointerTo's to the required kind of actual pointer. | |
To & | operator* () const |
To * | operator-> () const |
ThreadSafePointerTo< T > & | operator= (To *ptr) |
ThreadSafePointerTo< T > & | operator= (const ThreadSafePointerTo< T > ©) |
To * | p () const |
Returns an ordinary pointer instead of a ThreadSafePointerTo. |

void ThreadSafePointerTo< T >::clear | ( | ) | [inline] |
A convenient way to set the ThreadSafePointerTo object to NULL.
(Assignment to a NULL pointer also works, of course.)
Reimplemented from ThreadSafePointerToBase< T >.
Definition at line 68 of file threadSafePointerTo.h.
bool ThreadSafePointerTo< 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.

ThreadSafePointerTo< T >::operator T * | ( | ) | const [inline] |
We also have the typecast operator to automatically convert ThreadSafePointerTo'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.

ThreadSafePointerTo< T >::To * ThreadSafePointerTo< T >::p | ( | ) | const [inline] |
Returns an ordinary pointer instead of a ThreadSafePointerTo.
Useful to work around compiler problems, particularly for implicit upcasts.
