Constructor Detail

SelectChannelEndPoint

public SelectChannelEndPoint(java.nio.channels.SocketChannel channel,
                             SelectorManager.SelectSet selectSet,
                             java.nio.channels.SelectionKey key)

Method Detail

getSelectionKey

public java.nio.channels.SelectionKey getSelectionKey()

getSelectManager

public SelectorManager getSelectManager()

getConnection

public Connection getConnection()

Specified by:

getConnection in interface ConnectedEndPoint

setConnection

public void setConnection(Connection connection)

Specified by:

setConnection in interface ConnectedEndPoint

schedule

public void schedule()

Called by selectSet to schedule handling

dispatch

public void dispatch()

Description copied from interface: AsyncEndPoint

Dispatch the endpoint to a thread to attend to it.

Specified by:

dispatch in interface AsyncEndPoint

scheduleIdle

public void scheduleIdle()

Description copied from interface: AsyncEndPoint

Schedule a call to the idle timeout

Specified by:

scheduleIdle in interface AsyncEndPoint

cancelIdle

public void cancelIdle()

Description copied from interface: AsyncEndPoint

Cancel a call to the idle timeout

Specified by:

cancelIdle in interface AsyncEndPoint

idleExpired

protected void idleExpired()

flush

public int flush(Buffer header,
                 Buffer buffer,
                 Buffer trailer)
          throws java.io.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:

java.io.IOException

flush

public int flush(Buffer buffer)
          throws java.io.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:

java.io.IOException

isReadyForDispatch

public boolean isReadyForDispatch()

Specified by:

isReadyForDispatch in interface AsyncEndPoint

Returns:

true if this endpoint can accept a dispatch. False if the endpoint cannot accept a dispatched (eg is suspended or already dispatched)

blockReadable

public boolean blockReadable(long timeoutMs)
                      throws java.io.IOException

Specified by:

blockReadable in interface EndPoint

Overrides:

Throws:

java.io.IOException

                      throws java.io.IOException

Specified by:

blockWritable in interface EndPoint

Overrides:

blockWritable in class ChannelEndPoint

Throws:

java.io.IOException

setWritable

public void setWritable(boolean writable)

Description copied from interface: AsyncEndPoint

Set the writable status. The writable status is considered next time the async scheduling is calculated.

Specified by:

setWritable in interface AsyncEndPoint

Parameters:

writable - true if the endpoint is known to be writable or false if it is known to not be writable.

scheduleWrite

public void scheduleWrite()

Description copied from interface: AsyncEndPoint

Schedule a write dispatch. Set the endpoint to not be writable and schedule a dispatch when it becomes writable.

Specified by:
