Method Detail

renewInterestMask

public void renewInterestMask(int mask)
                       throws ClosedChannelException

Renews interest in receiving notifications when the I/O operations identified by the specified mask are ready for the associated SelectableChannel. The specified mask identifies I/O operations with the same bit values as would a java.nio.SelectionKey for the same SelectableChannel. Some time after one of the operations specified in the mask is detected to be ready, the previously-registered SelectionHandler callback object will be invoked to handle the readiness event. An event for each operation specified will only be dispatched to the callback handler once for the invocation of this method; to re-register interest in subsequent readiness of the same operation for the given channel, this method must be invoked again.

Throws:

ClosedChannelException
