NioProcessor(java.util.concurrent.Executor executor)
Creates a new instance of NioProcessor.

protected java.util.Iterator<NioSession> |
allSessions()
|
protected void |
destroy(NioSession session)
Destroy the underlying client socket handle
|
protected void |
doDispose()
Dispose the resources used by this
IoProcessor for polling the
client connections. |
protected SessionState |
getState(NioSession session)
Get the state of a session (preparing, open, closed)
|
protected void |
init(NioSession session)
Initialize the polling of a session.
|
protected boolean |
isInterestedInRead(NioSession session)
is this session registered for reading
|
protected boolean |
isInterestedInWrite(NioSession session)
is this session registered for writing
|
protected boolean |
isReadable(NioSession session)
Is the session ready for reading
|
protected boolean |
isSelectorEmpty()
Say if the list of
IoSession polled by this IoProcessor
is empty |
protected boolean |
isWritable(NioSession session)
Is the session ready for writing
|
protected int |
read(NioSession session,
IoBuffer buf)
|
protected int |
select()
poll those sessions forever
|
protected int |
select(long timeout)
poll those sessions for the given timeout
|
protected java.util.Iterator<NioSession> |
selectedSessions()
Get an
Iterator for the list of IoSession found selected
by the last call of {@link AbstractPollingIoProcessor#select(int) |
protected void |
setInterestedInRead(NioSession session,
boolean isInterested)
register a session for reading
|
protected void |
setInterestedInWrite(NioSession session,
boolean isInterested)
register a session for writing
|
protected int |
transferFile(NioSession session,
FileRegion region,
int length)
Write a part of a file to a
IoSession , if the underlying API
isn't supporting system calls like sendfile(), you can throw a
UnsupportedOperationException so the file will be send using
usual AbstractPollingIoProcessor.write(AbstractIoSession, IoBuffer, int) call. |
protected void |
wakeup()
Interrupt the {@link AbstractPollingIoProcessor#select(int) call.
|
protected int |
write(NioSession session,
IoBuffer buf,
int length)
Write a sequence of bytes to a
IoSession , means to be called when
a session was found ready for writing. |
