public static SelectorRunner create(NIOTransport transport)
                             throws java.io.IOException

Throws:

java.io.IOException

wakeupSelector

public void wakeupSelector()

public NIOTransport getTransport()

getSelector

public java.nio.channels.Selector getSelector()

getRunnerThread

public java.lang.Thread getRunnerThread()

getState

public Transport.State getState()

postpone

public void postpone()

start

public void start()

stop

run

public void run()

Specified by:

run in interface java.lang.Runnable

doSelect

protected boolean doSelect()

This method handle the processing of all Selector's interest op (OP_ACCEPT,OP_READ,OP_WRITE,OP_CONNECT) by delegating to its Handler. By default, all java.nio.channels.Selector operations are implemented using SelectorHandler. All SelectionKey operations are implemented by SelectionKeyHandler. Finally, ProtocolChain creation/re-use are implemented by InstanceHandler.

getPendingTasks

public java.util.Queue<SelectorHandlerTask> getPendingTasks()

getPostponedTasks

public java.util.Queue<SelectorHandlerTask> getPostponedTasks()

obtainPostponedTasks

public java.util.Queue<SelectorHandlerTask> obtainPostponedTasks()

getLastSelectedKeysCount

public int getLastSelectedKeysCount()

Number of SelectionKeys, which were selected last time. Operation is not thread-safe.

Returns:

number of SelectionKeys, which were selected last time.

switchToNewSelector

protected final void switchToNewSelector()
                                  throws java.io.IOException

Throws:

java.io.IOException
