Method Summary

Modifier and Type	Method	Description
void	engineStarting(EngineHandlerContext context)	Called when the engine is started to allow handlers to prepare for use based on the configuration state at start of the engine.
void	handlerAdded(EngineHandlerContext context)	Called when the handler is successfully added to the EnginePipeline and will later be initialized before use.
void	handleRead(EngineHandlerContext context, HeaderEnvelope header)	Handle the receipt of an incoming AMQP Header or SASL Header based on the current state of this handler.
void	handleRead(EngineHandlerContext context, IncomingAMQPEnvelope frame)	Handle the receipt of an incoming AMQP envelope based on the current state of this handler.
void	handleRead(EngineHandlerContext context, SASLEnvelope frame)	Handle the receipt of an incoming SASL performative based on the current state of this handler.
void	handlerRemoved(EngineHandlerContext context)	Called when the handler is successfully removed to the EnginePipeline.
void	handleWrite(EngineHandlerContext context, HeaderEnvelope frame)	Handles write of AMQPHeader either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)
void	handleWrite(EngineHandlerContext context, OutgoingAMQPEnvelope frame)	Handles write of AMQP performative envelope either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)
void	handleWrite(EngineHandlerContext context, SASLEnvelope frame)	Handles write of SaslPerformative either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)

ProtonSaslHandler

public ProtonSaslHandler()

Method Details

isDone

public boolean isDone()

Returns:

true if the SASL exchange has finished (succeed or failed).

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.

handlerRemoved

public void handlerRemoved(EngineHandlerContext context)

Description copied from interface: EngineHandler

Called when the handler is successfully removed to the EnginePipeline.

Specified by:

handlerRemoved in interface EngineHandler

Parameters:

context - The context that is assigned to this handler.

engineStarting

public void engineStarting(EngineHandlerContext context)

Description copied from interface: EngineHandler

Called when the engine is started to allow handlers to prepare for use based on the configuration state at start of the engine. A handler can fail the engine start by throwing an exception.

Specified by:

engineStarting in interface EngineHandler

Parameters:

context - The context for this handler which can be used to forward the event to the next 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,
 SASLEnvelope frame)

Description copied from interface: EngineHandler

Handle the receipt of an incoming SASL performative 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

frame - The SASL envelope that wraps the received SaslPerformative.

handleRead

public void handleRead(EngineHandlerContext context,
 IncomingAMQPEnvelope frame)

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

frame - The AMQP envelope that wraps the received Performative.

handleWrite

public void handleWrite(EngineHandlerContext context,
 HeaderEnvelope frame)

Description copied from interface: EngineHandler

Handles write of AMQPHeader either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)

Specified by:

handleWrite in interface EngineHandler

Parameters:

context - The EngineHandlerContext associated with this EngineHandler instance.

frame - The HeaderEnvelope instance to write.

handleWrite

public void handleWrite(EngineHandlerContext context,
 OutgoingAMQPEnvelope frame)

Description copied from interface: EngineHandler

Handles write of AMQP performative envelope either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)

Specified by:

handleWrite in interface EngineHandler

Parameters:

context - The EngineHandlerContext associated with this EngineHandler instance.

frame - The OutgoingAMQPEnvelope instance to write.

handleWrite

public void handleWrite(EngineHandlerContext context,
 SASLEnvelope frame)

Description copied from interface: EngineHandler

Handles write of SaslPerformative either by directly writing it to the output target or by converting it to bytes and firing a write using the ProtonBuffer based API in EngineHandlerContext.fireWrite(ProtonBuffer, Runnable)

Specified by:

handleWrite in interface EngineHandler

Parameters:

context - The EngineHandlerContext associated with this EngineHandler instance.

frame - The SASLEnvelope instance to write.
