Method Detail

onPreAdd

public void onPreAdd(IoFilterChain parent,
            String name,
            IoFilter.NextFilter nextFilter)
              throws Exception

Description copied from class: IoFilterAdapter

Invoked before this filter is added to the specified parent. Please note that this method can be invoked more than once if this filter is added to more than one parents. This method is not invoked before IoFilter.init() is invoked.

Specified by:

onPreAdd in interface IoFilter

Overrides:

onPreAdd in class IoFilterAdapter

Parameters:

parent - the parent who called this method

name - the name assigned to this filter

nextFilter - the IoFilter.NextFilter for this filter. You can reuse this object until this filter is removed from the chain.

Throws:

Exception

onPostRemove

public void onPostRemove(IoFilterChain parent,
                String name,
                IoFilter.NextFilter nextFilter)
                  throws Exception

Description copied from class: IoFilterAdapter

Invoked after this filter is removed from the specified parent. Please note that this method can be invoked more than once if this filter is removed from more than one parents. This method is always invoked before IoFilter.destroy() is invoked.

Specified by:

onPostRemove in interface IoFilter

Overrides:

onPostRemove in class IoFilterAdapter

Parameters:

parent - the parent who called this method

name - the name assigned to this filter

nextFilter - the IoFilter.NextFilter for this filter. You can reuse this object until this filter is removed from the chain.

Throws:

Exception

messageReceived

public void messageReceived(IoFilter.NextFilter nextFilter,
                   IoSession session,
                   Object message)
                     throws Exception

Description copied from class: IoFilterAdapter

Filters IoHandler.messageReceived(IoSession,Object) event.

Specified by:

messageReceived in interface IoFilter

Overrides:

messageReceived in class IoFilterAdapter

Throws:

Exception

doFilterWrite

protected Object doFilterWrite(IoFilter.NextFilter nextFilter,
                   IoSession session,
                   WriteRequest writeRequest)
                        throws Exception

Specified by:

doFilterWrite in class WriteRequestFilter

Throws:

Exception

sessionClosed

public void sessionClosed(IoFilter.NextFilter nextFilter,
                 IoSession session)
                   throws Exception

Description copied from class: IoFilterAdapter

Filters IoHandler.sessionClosed(IoSession) event.

Specified by:

sessionClosed in interface IoFilter

Overrides:

sessionClosed in class IoFilterAdapter

Throws:

Exception

createRequestStore

protected Map<Object,Request> createRequestStore(IoSession session)

Returns a Map which stores messageId-Request pairs whose Responses are not received yet. Please override this method if you need to use other Map implementation than the default one (HashMap).

createUnrespondedRequestStore

protected Set<Request> createUnrespondedRequestStore(IoSession session)

Returns a Set which stores Request whose Responses are not received yet. Please override this method if you need to use other Set implementation than the default one (LinkedHashSet). Please note that the Iterator of the returned Set have to iterate its elements in the insertion order to ensure that RequestTimeoutExceptions are thrown in the order which Requests were written. If you don't need to guarantee the order of thrown exceptions, any Set implementation can be used.

destroyRequestStore

protected void destroyRequestStore(Map<Object,Request> requestStore)

Releases any resources related with the Map created by createRequestStore(IoSession). This method is useful if you override createRequestStore(IoSession).

Parameters:

requestStore - what you returned in createRequestStore(IoSession)

destroyUnrespondedRequestStore

protected void destroyUnrespondedRequestStore(Set<Request> unrespondedRequestStore)

Releases any resources related with the Set created by createUnrespondedRequestStore(IoSession). This method is useful if you override createUnrespondedRequestStore(IoSession).

Parameters:

unrespondedRequestStore - what you returned in createUnrespondedRequestStore(IoSession)
