ThreadSafePointerTo< T > Class Template Reference

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...

Detailed Description

template<class T>
class ThreadSafePointerTo< T >

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.

Member Function Documentation

◆ operator T *()

template<class T >
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.

Definition at line 66 of file threadSafePointerTo.I.

References AtomicAdjustDummyImpl::get_ptr().

◆ p()

template<class T >
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.
