Constructor Details

SelectorThread

public SelectorThread()
               throws IOException

Set up the SelectorThread with an unbounded queue for incoming accepts.

Throws:

IOException - if a selector cannot be created

SelectorThread

public SelectorThread(int maxPendingAccepts)
               throws IOException

Set up the SelectorThread with an bounded queue for incoming accepts.

Throws:

IOException - if a selector cannot be created

SelectorThread

public SelectorThread(BlockingQueue<TNonblockingTransport> acceptedQueue)
               throws IOException

Set up the SelectorThread with a specified queue for connections.

Parameters:

acceptedQueue - The BlockingQueue implementation for holding incoming accepted connections.

Throws:

IOException - if a selector cannot be created.

Method Details

addAcceptedConnection

public boolean addAcceptedConnection(TNonblockingTransport accepted)

Hands off an accepted connection to be handled by this thread. This method will block if the queue for new connections is at capacity.

Parameters:

accepted - The connection that has been accepted.

Returns:

true if the connection has been successfully added.

run

public void run()

The work loop. Handles selecting (read/write IO), dispatching, and managing the selection preferences of all existing connections.

Specified by:

run in interface Runnable

Overrides:

run in class Thread

createFrameBuffer

protected AbstractNonblockingServer.FrameBuffer createFrameBuffer(TNonblockingTransport trans,
 SelectionKey selectionKey,
 AbstractNonblockingServer.AbstractSelectThread selectThread)
                                                           throws TTransportException

Throws:
