Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getName

public java.lang.String getName()

Specified by:

getName in class Protocol

init

public void init()
          throws java.lang.Exception

Description copied from class: Protocol

Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.

Overrides:

init in class Protocol

Throws:

java.lang.Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception

start

public void start()
           throws java.lang.Exception

Description copied from class: Protocol

This method is called on a Channel.connect(String). Starts work. Protocols are connected and queues are ready to receive events. Will be called from bottom to top. This call will replace the START and START_OK events.

Overrides:

start in class Protocol

Throws:

java.lang.Exception - Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, so Channel.connect(String) will throw an exception

down

public java.lang.Object down(Event evt)

Caller by the layer above this layer. Usually we just put this Message into the send queue and let one or more worker threads handle it. A worker thread then removes the Message from the send queue, performs a conversion and adds the modified Message to the send queue of the layer below it, by calling Down).

Overrides:

down in class Protocol
