Barrier [constructor] | Constructors |
~Barrier [destructor] | Wait for all signaled threads to unblock and destroy this barrier. (See wait and timedWait below for the meaning of signaled.) Note that the behavior is undefined if a barrier is destroyed while one or more threads are waiting on it. |
arrive | Arrive on this barrier. If this is the last required arrival, signal all the threads that are currently waiting on this barrier to unblock and reset the state of this barrier to its initial state. |
clockType | Return the clock type used for timeouts. |
numArrivals | Return the required number of arrivals before all waiting threads will unblock. |
numThreads | Return the required number of arrivals before all waiting threads will unblock. |
timedWait | timedWait overloads |
wait | Arrive and block until the required number of arrivals have occurred. Then signal all the threads that are currently waiting on this barrier to unblock and reset the state of this barrier to its initial state. Note that generally wait and timedWait should not be used together, for reasons explained in the documentation of timedWait. |
