Method Detail

setKey

void setKey(SelectionKey key)

dispatch

void dispatch()
        throws IOException

Dispatch the endpoint by arranging for a thread to service it. Either a blocked thread is woken up or the endpoint is passed to the server job queue. If the thread is dispatched and then the selection key is modified so that it is no longer selected.

Throws:

IOException

undispatch

private void undispatch()

Called when a dispatched thread is no longer handling the endpoint. The selection key operations are updated.

fill

public int fill(Buffer buffer)
         throws IOException

Description copied from interface: EndPoint

Fill the buffer from the current putIndex to it's capacity from whatever byte source is backing the buffer. The putIndex is increased if bytes filled. The buffer may chose to do a compact before filling.

Specified by:

fill in interface EndPoint

Overrides:

fill in class ChannelEndPoint

Returns:

an int value indicating the number of bytes filled or -1 if EOF is reached.

Throws:

IOException

flush

public int flush(Buffer header,
                 Buffer buffer,
                 Buffer trailer)
          throws IOException

Description copied from interface: EndPoint

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done. The passed header/trailer buffers are written before/after the contents of this buffer. This may be done either as gather writes, as a poke into this buffer or as several writes. The implementation is free to select the optimal mechanism.

Specified by:

flush in interface EndPoint

Overrides:

flush in class ChannelEndPoint

Parameters:

header - A buffer to write before flushing this buffer. This buffers getIndex is updated.

buffer - The buffer to flush. This buffers getIndex is updated.

trailer - A buffer to write after flushing this buffer. This buffers getIndex is updated.

Returns:

the total number of bytes written.

Throws:

IOException

flush

public int flush(Buffer buffer)
          throws IOException

Description copied from interface: EndPoint

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done.

Specified by:

flush in interface EndPoint

Overrides:

flush in class ChannelEndPoint

Parameters:

buffer - The buffer to flush. This buffers getIndex is updated.

Returns:

the number of bytes written

Throws:

IOException

isOpen

public boolean isOpen()

Specified by:

isOpen in interface EndPoint

Overrides:

isOpen in class ChannelEndPoint

blockReadable

public void blockReadable(long timeoutMs)

Specified by:

blockReadable in interface EndPoint

Overrides:

blockReadable in class ChannelEndPoint

blockWritable

public void blockWritable(long timeoutMs)

Specified by:

blockWritable in interface EndPoint

Overrides:

blockWritable in class ChannelEndPoint

updateKey

private void updateKey()

Updates selection key. Adds operations types to the selection key as needed. No operations are removed as this is only done during dispatch

run

public void run()

Specified by:

run in interface Runnable

close

public void close()
           throws IOException

Description copied from interface: EndPoint

Close any backing stream associated with the buffer

Specified by:

close in interface EndPoint

Overrides:

close in class ChannelEndPoint

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
