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
GrizzlyFuture<ReadResult>	read(Connection connection, CompletionHandler<ReadResult> completionHandler)
void	setInterested(IOEvent ioEvent, boolean isInterested) Set the the i/o event, this Processor is interested in
GrizzlyFuture<WriteResult>	write(Connection connection, java.lang.Object dstAddress, java.lang.Object message, CompletionHandler<WriteResult> completionHandler)

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)
                        throws java.io.IOException

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

Throws:

java.io.IOException

read

GrizzlyFuture<ReadResult> read(Connection connection,
                               CompletionHandler<ReadResult> completionHandler)
                               throws java.io.IOException

Throws:

java.io.IOException

write

GrizzlyFuture<WriteResult> write(Connection connection,
                                 java.lang.Object dstAddress,
                                 java.lang.Object message,
                                 CompletionHandler<WriteResult> completionHandler)
                                 throws java.io.IOException

Throws:

java.io.IOException

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.
