- Method Detail
  - handler
```
EngineHandler handler()
```
    Returns:
    
    the EngineHandler that is associated with the context.
  - engine
```
Engine engine()
```
    Returns:
    
    the Engine where this handler is registered.
  - name
```
String name()
```
    Returns:
    
    the name that assigned to this EngineHandler when added to the EnginePipeline.
  - fireEngineStarting
```
void fireEngineStarting()
```
    Fires the engine starting event into the next handler in the EnginePipeline chain.
  - fireEngineStateChanged
```
void fireEngineStateChanged()
```
    Fires the engine state changed event into the next handler in the EnginePipeline chain. The state change events occur after the engine starting event and generally signify that the engine has been shutdown normally.
  - fireFailed
```
void fireFailed(EngineFailedException failure)
```
    Fires the Engine failed event into the next handler in the EnginePipeline chain.
    
    Parameters:
    
    failure - The exception that describes the conditions under which the engine failed.
  - fireRead
```
void fireRead(ProtonBuffer buffer)
```
    Fires a read of ProtonBuffer events into the previous handler in the EnginePipeline for further processing.
    
    Parameters:
    
    buffer - The ProtonBuffer that carries the bytes read.
  - fireRead
```
void fireRead(HeaderEnvelope header)
```
    Fires a read of HeaderFrame events into the previous handler in the EnginePipeline for further processing.
    
    Parameters:
    
    header - The HeaderEnvelope that carries the header bytes read.
  - fireRead
```
void fireRead(SASLEnvelope envelope)
```
    Fires a read of SASL events into the previous handler in the EnginePipeline for further processing.
    
    Parameters:
    
    envelope - The SASLEnvelope that carries the SASL performative read.
  - fireRead
```
void fireRead(IncomingAMQPEnvelope envelope)
```
    Fires a read of IncomingProtocolFrame events into the previous handler in the EnginePipeline for further processing.
    
    Parameters:
    
    envelope - The IncomingAMQPEnvelope that carries the AMQP performative read.
  - fireWrite
```
void fireWrite(OutgoingAMQPEnvelope envelope)
```
    Fires a write of OutgoingAMQPEnvelope events into the next handler in the EnginePipeline for further processing.
    
    Parameters:
    
    envelope - The OutgoingAMQPEnvelope that carries the AMQP performative being written.
  - fireWrite
```
void fireWrite(SASLEnvelope envelope)
```
    Fires a write of SASLEnvelope events into the next handler in the EnginePipeline for further processing.
    
    Parameters:
    
    envelope - The SASLEnvelope that carries the SASL performative being written.
  - fireWrite
```
void fireWrite(HeaderEnvelope envelope)
```
    Fires a write of HeaderFrame events into the next handler in the EnginePipeline for further processing.
    
    Parameters:
    
    envelope - The HeaderEnvelope that carries the AMQP Header being written.
  - fireWrite
```
void fireWrite(ProtonBuffer buffer,
               Runnable ioComplete)
```
    Fires a write of ProtonBuffer events into the next handler in the EnginePipeline for further processing.
    
    Parameters:
    
    buffer - The ProtonBuffer that carries the bytes being written.
    
    ioComplete - An optional Runnable callback that is signaled when the I/O completes successfully.
