Method Detail

suspend

public void suspend(java.lang.Object monitor)
             throws java.lang.InterruptedException

Description copied from interface: Waiter

Suspend the current request and release locks. When the request is resumed, any of the following may happen:

• suspend returns.
• suspend throws InterruptedException.
• Call is retried with the same Waiter.

Therefore the request must be reentrant.

Specified by:

suspend in interface Waiter

Parameters:

monitor - the monitor to wait on if a blocking implementation is used.

Throws:

java.lang.InterruptedException - if the call timed out.

resume

public void resume()

Description copied from interface: Waiter

Signal that the asynchronous call should be resumed. This may mean that a waiting call to suspend() returns, or that the asynchronous call is simply retried.

Specified by:
