Interface Processor<E extends Context>

All Known Subinterfaces:

AsyncQueueProcessor, AsyncQueueReader<L>, AsyncQueueWriter<L>, CallbackHandler, FilterChain

All Known Implementing Classes:

AbstractCallbackHandler, AbstractFilterChain, AbstractNIOAsyncQueueReader, AbstractNIOAsyncQueueWriter, AbstractProcessor, CallbackHandlerAdapter, DefaultFilterChain, ListFacadeFilterChain, ProcessorWrapper, StandaloneProcessor, TCPNIOAsyncQueueReader, TCPNIOAsyncQueueWriter, TCPNIOConnectorHandler.ConnectorEventProcessor, TCPNIOServerConnection.AcceptorEventProcessor, UDPNIOAsyncQueueReader, UDPNIOAsyncQueueWriter

public interface Processor<E extends Context>

Processor implementations are responsible for processing I/O events, which occur on connection.

Method Summary

void	afterProcess(E context) Method will be called by framework after Processor execution, so it can release associated resources.
void	beforeProcess(E context) Method will be called by framework before executing this Processor.
E	context() Creates Context
boolean	isInterested(IOEvent ioEvent) Is this Processor interested in processing the i/o event
ProcessorResult	process(E context) Method will be called by framework to process some event, which occured on a connection
void	setInterested(IOEvent ioEvent, boolean isInterested) Set the the i/o event, this Processor is interested in

Method Detail

context

E context()

Creates Context

Returns:

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

beforeProcess

void beforeProcess(E context)
                   throws IOException

Method will be called by framework before executing this Processor.

Parameters:

context - processing context

Throws:

IOException

process

ProcessorResult process(E context)
                        throws IOException

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

Parameters:

context - processing context

Returns:

the result of I/O event processing

Throws:

IOException

afterProcess

void afterProcess(E context)
                  throws IOException

Method will be called by framework after Processor execution, so it can release associated resources.

Parameters:

context - processing context

Throws:

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.
