ProtonPerformativeHandler

public ProtonPerformativeHandler()

Method Detail

handlerAdded

public void handlerAdded(EngineHandlerContext context)

Description copied from interface: EngineHandler

Called when the handler is successfully added to the EnginePipeline and will later be initialized before use.

Specified by:

handlerAdded in interface EngineHandler

Parameters:

context - The context that is assigned to this handler.

handleRead

public void handleRead(EngineHandlerContext context,
                       HeaderEnvelope header)

Description copied from interface: EngineHandler

Handle the receipt of an incoming AMQP Header or SASL Header based on the current state of this handler.

Specified by:

handleRead in interface EngineHandler

Parameters:

context - The context for this handler which can be used to forward the event to the next handler

header - The AMQP Header envelope that wraps the received header instance.

handleRead

public void handleRead(EngineHandlerContext context,
                       IncomingAMQPEnvelope envelope)

Description copied from interface: EngineHandler

Handle the receipt of an incoming AMQP envelope based on the current state of this handler.

Specified by:

handleRead in interface EngineHandler

Parameters:

context - The context for this handler which can be used to forward the event to the next handler

envelope - The AMQP envelope that wraps the received Performative.

engineFailed

public void engineFailed(EngineHandlerContext context,
                         EngineFailedException failure)

Description copied from interface: EngineHandler

Called when the engine has transitioned to a failed state and cannot process any additional input or output. The handler can free and resources used for normal operations at this point as the engine is now considered shutdown.

Specified by:

engineFailed in interface EngineHandler

Parameters:

context - The context for this handler which can be used to forward the event to the next handler

failure - The failure that triggered the engine to cease operations.
