executeIoEvent

public boolean executeIoEvent(Connection connection,
                              IOEvent ioEvent,
                              boolean isIoEventEnabled)
                       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.

Parameters:

connection - the Connection upon which the provided IOEvent occurred.

ioEvent - the IOEvent that triggered execution of this strategy

isIoEventEnabled - true if IOEvent is still enabled on the Connection, or false if IOEvent was preliminary disabled or IOEvent is being simulated.

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

Overrides:

getThreadPoolFor in class AbstractIOStrategy

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

createDefaultWorkerPoolConfig

public ThreadPoolConfig createDefaultWorkerPoolConfig(Transport transport)

Specified by:

createDefaultWorkerPoolConfig in interface WorkerThreadPoolConfigProducer

Overrides:

createDefaultWorkerPoolConfig in class AbstractIOStrategy
