Method Detail

read

public void read(SocketAddress remoteAddress,
                 Object msg)

Description copied from interface: IDatagramHandler

Called when a new message was received and decoded from a remote end that is identified by the given remote address. This method is called when the associated session is configured with a codec pipeline in which the last decoder produces outbound object(s) of type different than the byte[] and ByteBuffer.

The method is only called for sessions created with a disconnected datagram channel.

Parameters:

remoteAddress - address of the remote end.

msg - the message received from the remote end.

read

public void read(Object msg)

Description copied from interface: IHandler

Called when a new message was read and decoded from the input buffer. This method is called when the associated session is configured with a codec pipeline in which the last decoder produces outbound object(s) of type different than the byte[] and ByteBuffer.

Parameters:

msg - the message that was read and decoded from the input buffer.

timer

public void timer(Object event)

Description copied from interface: IHandler

Called to notify about an expiration of the timer identified by the specified event object.

Specified by:

timer in interface IHandler

Overrides:

timer in class AbstractHandler

Parameters:

event - the event object that identifies the timer

event

public void event(SessionEvent event)

Description copied from interface: IHandler

Called to notify about a change of the associated session state.

Specified by:

event in interface IHandler

Overrides:

event in class AbstractHandler

Parameters:

event - an event related with the change of the session state

See Also:

SessionEvent

exception

public void exception(Throwable e)

Description copied from interface: IHandler

Called to notify about an exception caught during processing of I/O or protocol related operations. After returning form this method the associated session will be quickly closed.

Specified by:

exception in interface IHandler

Overrides:

exception in class AbstractHandler

Parameters:

e - the exception caught

incident

public boolean incident(SessionIncident incident,
                        Throwable t)

Description copied from interface: IHandler

Called to notify about an incident that occurred during processing of I/O or protocol related operations.

Specified by:

incident in interface IHandler

Overrides:

incident in class AbstractHandler

Parameters:

incident - an incident that occurred

t - an exception that is related with the incident or null

Returns:

true to indicate that the incident was handled and the default action should not be executed by the SNF4J framework underneath.

getFactory

public ISessionStructureFactory getFactory()

Description copied from interface: IHandler

Returns the factory object that will be used to configure the internal structure of the associated session.

Specified by:

getFactory in interface IHandler

Overrides:

getFactory in class AbstractHandler

Returns:

the factory object

See Also:

ISessionStructureFactory

getConfig

public ISessionConfig getConfig()

Description copied from interface: IHandler

Returns the configuration object that will be used to configure the behavior of the associated session.

Specified by:

getConfig in interface IHandler

Overrides:

getConfig in class AbstractHandler

Returns:

the configuration object
