Detailed Description

template<class T>
class proton::returned< T >

A return type for container methods.

Thread safety - Container method return values are thread-unsafe. A single-threaded application can safely assign the returned<T> value to a plain T. A multithreaded application must ignore the returned value because it may already be invalid by the time the function returns. Multithreaded applications can safely access the value inside messaging_handler functions.
