Constructor Detail

WorkerThreadStrategy

public WorkerThreadStrategy(Transport transport)

WorkerThreadStrategy

public WorkerThreadStrategy(Executor sameThreadProcessorExecutor,
                            Executor workerThreadProcessorExecutor)

Method Detail

prepare

public Object prepare(Connection connection,
                      IOEvent ioEvent)

Prepare Strategy for processing IOEvent, occured on the Connection. At this phase Strategy may initialize and return context data, which will be passed further into executeProcessor and isTerminateThread methods.

Specified by:

prepare in interface Strategy

Parameters:

connection - Connection, on which IOEvent occured.

ioEvent - IOEvent.

Returns:

context/state, associated with the IOEvent processing.

executeProcessor

public void executeProcessor(Object strategyContext,
                             ProcessorRunnable processorRunnable)
                      throws IOException

Execute ProcessorRunnable task.

Specified by:

executeProcessor in interface Strategy

Parameters:

strategyContext - context object, initialized on "prepare" phase.

processorRunnable - the ProcessorRunnable task to be executed.

Throws:

IOException

isTerminateThread

public boolean isTerminateThread(Object strategyContext)

This method may be called by runner Thread after task will be executed. Strategy may instruct the caller to release current thread, after task execution will be completed.

Specified by:

isTerminateThread in interface Strategy

Parameters:

strategyContext - Strategy context, initialized on "prepare" phase.

Returns:

true, to instruct caller to release the current Thread, or false otherwise.
