Examples of java.nio.channels.SelectableChannel.blockingLock()

java.nio.channels.SelectableChannel.blockingLock()
Retrieves the object upon which the {@link #configureBlocking configureBlocking} and {@link #register register} methods synchronize.This is often useful in the implementation of adaptors that require a specific blocking mode to be maintained for a short period of time.
@return The blocking-mode lock object
