Constructor Detail

CbJxMessenger

public CbJxMessenger(CbJxTransport transport,
                     EndpointAddress dest,
                     Object hintIgnored)
              throws IOException
constructor

Parameters:
dest - the destination address
Throws:
IOException

CbJxMessenger

public CbJxMessenger(CbJxTransport transport,
                     EndpointAddress dest)
              throws IOException
constructor

Parameters:
dest - the destination address
Throws:
IOException
Method Detail

closeImpl

public void closeImpl()
Close connection. May fail current send.

Specified by:
closeImpl in class BlockingMessenger

getLogicalDestinationImpl

public EndpointAddress getLogicalDestinationImpl()
Obtain the logical destination address from the implementer (a transport for example).

Specified by:
getLogicalDestinationImpl in class BlockingMessenger

isIdleImpl

public boolean isIdleImpl()
return true if this messenger has not been used for a long time. The definition of long time is: "sufficient such that closing it is worth the cost of having to re-open". A messenger should self close if it thinks it meets the definition of idle. BlockingMessenger leaves the evaluation to the transport but does the work automatically. Important: if self destruction is used, this method must work; not just return false. See the constructor. In general, if closeImpl does not need to do anything, then self destruction is not needed.

Since CbJx is a virtual transport and consumes very few resources there is no point to doing idle teardown.

Specified by:
isIdleImpl in class BlockingMessenger
Returns:
true if theis messenger is, by it's own definition, idle.

sendMessageBImpl

public void sendMessageBImpl(Message msg,
                             String service,
                             String serviceParam)
                      throws IOException
Send a message blocking as needed until the message is sent.

Specified by:
sendMessageBImpl in class BlockingMessenger
Parameters:
msg - The message to send.
service - The destination service.
serviceParam - The destination serivce param.
Throws:
IOException - Thrown for errors encountered while sending the message.

sendTo

void sendTo(Message msg)
      throws IOException
Send a message via the underlying messenger.

Parameters:
msg - The message to send to the remote peer.
Throws:
IOException - if there was a problem sending the message.
