protected java.util.Iterator<AprSession> |
allSessions()
|
protected void |
destroy(AprSession session)
Destroy the underlying client socket handle
|
protected void |
dispose0()
Dispose the resources used by this
IoProcessor for polling
the client connections |
protected void |
init(AprSession session)
Initialize the polling of a session.
|
protected boolean |
isInterestedInRead(AprSession session)
is this session registered for reading
|
protected boolean |
isInterestedInWrite(AprSession session)
is this session registered for writing
|
protected boolean |
isReadable(AprSession 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(AprSession session)
Is the session ready for writing
|
protected int |
read(AprSession session,
IoBuffer buffer)
|
protected boolean |
select(int timeout)
poll those sessions for the given timeout
|
protected java.util.Iterator<AprSession> |
selectedSessions()
Get an
Iterator for the list of IoSession found selected
by the last call of {@link AbstractPollingIoProcessor#select(int) |
protected void |
setInterestedInRead(AprSession session,
boolean value)
register a session for reading
|
protected void |
setInterestedInWrite(AprSession session,
boolean value)
register a session for writing
|
protected AbstractPollingIoProcessor.SessionState |
state(AprSession session)
Get the sate of a session (preparing, open, closed)
|
protected int |
transferFile(AprSession 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(AprSession 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. |
