he SignaledBarrier has two states: Open and Closed. In Open state the member function SignaledBarrier::waitForOpen returns immediately. In the Closed state it blocks until the state changes to Open. The thread-safe member functions SignaledBarrier::open and SignaledBarrier::close control the state.

The following is the public interface of SignaledBarrier:

class SignaledBarrier : boost::noncopyable




void waitForOpen() volatile;

void open() volatile;

void close() volatile;


The Signaled barrier should be accessed via the following statements:

#include <ots/threading/SignaledBarrier.hpp>

#include <ots/otsConfig.hpp>

typedef ots::config::SignaledBarrier::type SignaledBarrier.

The member functions throw either ots::config::ThreadResourceError (=boost::thread_resource_error by default ots::config setting) or ots::ThreadInterrupted (=boost::thread_interrupted).
