Method Detail

createDefaultWorkerPoolConfig

public ThreadPoolConfig createDefaultWorkerPoolConfig(Transport transport)

Specified by:

createDefaultWorkerPoolConfig in interface WorkerThreadPoolConfigProducer

executeIoEvent

public final boolean executeIoEvent(Connection connection,
                                    IOEvent ioEvent)
                             throws IOException

Description copied from interface: IOStrategy

The SelectorRunner will invoke this method to allow the strategy implementation to decide how the IOEvent will be handled.

Specified by:

executeIoEvent in interface IOStrategy

Parameters:

connection - the Connection upon which the provided IOEvent occurred.

ioEvent - the IOEvent that triggered execution of this strategy

Returns:

true, if this thread should keep processing IOEvents on the current and other Connections, or false if this thread should hand-off the farther IOEvent processing on any Connections, which means IOStrategy is becoming responsible for continuing IOEvent processing (possibly starting new thread, which will handle IOEvents).

Throws:

IOException - if an error occurs processing the IOEvent.

getThreadPoolFor

public Executor getThreadPoolFor(Connection connection,
                                 IOEvent ioEvent)

Description copied from interface: IOStrategy

Returns an Executor to be used to run given ioEvent processing for the given connection. A null value will be returned if the ioEvent should be executed in the kernel thread.

Specified by:

getThreadPoolFor in interface IOStrategy

Parameters:

connection - Connection

ioEvent - the event to get the Executor for

Returns:

an Executor to be used to run given ioEvent processing for the given connection

isReadWrite

protected static boolean isReadWrite(IOEvent ioEvent)

fireIOEvent

protected static void fireIOEvent(Connection connection,
                                  IOEvent ioEvent,
                                  IOEventLifeCycleListener listener,
                                  Logger logger)
