All Implemented Interfaces:
Messenger, SimpleSelectable

 class RouterMessenger
extends BlockingMessenger

Messenger for destinations which are logical peers. This messenger is used only at the origin of routes. Incoming messages that are being forwarded to another peer do not use this form of messenger.

Constructor Detail

RouterMessenger

public RouterMessenger(EndpointAddress dstAddress,
                       EndpointRouter r,
                       Object hint)
                throws IOException
Constructor for a RouterMessenger.

Parameters:
dstAddress - the peer which is the final destination of the message.
r - the router which this messenger is servicing.
hint - potential hint information that we passed
Throws:
IOException - Thrown if the messenger cannot be constructed for this destination.
Method Detail

getLogicalDestinationImpl

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

Specified by:
getLogicalDestinationImpl in class BlockingMessenger

closeImpl

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

Specified by:
closeImpl 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.

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

sendMessageBImpl

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

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