Method Summary

boolean	isInterested(IOEvent ioEvent) Is this Processor interested in processing the i/o event
E	obtainContext(Connection connection) Creates Context
ProcessorResult	process(E context) Method will be called by framework to process some event, which occurred on a connection
void	read(Connection connection, CompletionHandler<ReadResult> completionHandler)
void	setInterested(IOEvent ioEvent, boolean isInterested) Set the the i/o event, this Processor is interested in
void	write(Connection connection, java.lang.Object dstAddress, java.lang.Object message, CompletionHandler<WriteResult> completionHandler, PushBackHandler pushBackHandler)

Method Detail

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

ProcessorResult process(E context)

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,
           java.lang.Object dstAddress,
           java.lang.Object message,
           CompletionHandler<WriteResult> completionHandler,
           PushBackHandler pushBackHandler)

isInterested

boolean isInterested(IOEvent ioEvent)

Is this Processor interested in processing the i/o event

Parameters:

ioEvent -

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.
