Method Details

obtainContext

E obtainContext(Connection connection)

Creates Context

Parameters:

connection - Connection to obtain processor for.

Returns:

Context, or null, if default Context could be used.

process

Method will be called by framework to process some event, which occurred on a connection

Parameters:

context - processing context

Returns:

the result of I/O event processing

read

void read(Connection connection,
 CompletionHandler<ReadResult> completionHandler)

write

void write(Connection connection,
 Object dstAddress,
 Object message,
 CompletionHandler<WriteResult> completionHandler)

write

void write(Connection connection,
 Object dstAddress,
 Object message,
 CompletionHandler<WriteResult> completionHandler,
 MessageCloner messageCloner)

write

@Deprecated
void write(Connection connection,
 Object dstAddress,
 Object message,
 CompletionHandler<WriteResult> completionHandler,
 PushBackHandler pushBackHandler)

Deprecated.

isInterested

boolean isInterested(IOEvent ioEvent)

Is this Processor interested in processing the i/o event

Parameters:

ioEvent - the event to check if the Processor is interested in

Returns:

true, if this Processor is interested and execution process will start, false otherwise.

setInterested

void setInterested(IOEvent ioEvent,
 boolean isInterested)

Set the the i/o event, this Processor is interested in

Parameters:

ioEvent - IOEvent

isInterested - true, if Processor is interested in processing of the I/O event, or false otherwise.
