version:
1.04 |
| Constructor Summary | |
| public | Semaphore()
Create semaphore with zero counter value. | | public | Semaphore(int initValue)
Create semaphore with specified non-negative counter value. |
| Method Summary | |
| public synchronized void | signal()
Increment value of the counter. | | public synchronized void | waitSemaphore()
Wait for non-zero value of counter. | | public synchronized boolean | waitSemaphore(long timeout)
Wait at most timeout miliseconds for non-zero value
of counter.
Parameters:
timeout - the maximum time to wait in milliseconds. |
| counter | | protected int counter(Code) | | |
| Semaphore | | public Semaphore()(Code) | | Create semaphore with zero counter value.
|
| Semaphore | | public Semaphore(int initValue)(Code) | | Create semaphore with specified non-negative counter value.
Parameters:
initValue - initial value of semaphore counter |
| signal | | public synchronized void signal()(Code) | | Increment value of the counter. If there are waiting threads, exactly
one of them will be awaken.
|
| waitSemaphore | | public synchronized boolean waitSemaphore(long timeout) throws InterruptedException(Code) | | Wait at most timeout miliseconds for non-zero value
of counter.
Parameters:
timeout - the maximum time to wait in milliseconds. true if counter is not zero, falseif wait() was terminated due to timeout expiration. |
