Interface MessageDispatchTarget

public interface MessageDispatchTarget

It enables client applications to add a topic subscription to MessageDispatcher instance with a blocking or non-blocking consumer. An instance of this type can be created by a factory method which is going to be added when this feature is made available. This factory method will take two parameters: - A mandatory Subscription instance of type Topic. - An optional XMLMessageListener instance. If null, this means that the MessageDispatchTarget has a blocking receiver. See getConsumer() for more information about the types of Consumers.

Method Summary

Consumer	getConsumer() If the MessageDispatchTarget instance is not yet subscribed with the MessageDispatcher, this method will return null.
XMLMessageListener	getMessageListener() Immutable.
Subscription	getSubscription() Immutable.
boolean	hasBlockingConsumer()

Method Detail

getMessageListener

XMLMessageListener getMessageListener()

Immutable. If non-null it indicates that the client application is using a non-blocking consumer

Returns:

result

getSubscription

Subscription getSubscription()

Immutable. It represents the Topic subscription matching the dispatch target.

Returns:

result

getConsumer

Consumer getConsumer()

If the MessageDispatchTarget instance is not yet subscribed with the MessageDispatcher, this method will return null. Once successfully subscribed with the MessageDispatcher (by calling addSubscription(...) on the MessageDispatcher), it will return a consumer instance. The returned consumer can be either blocking or non-blocking, if non-blocking, client applications will receive the matching messages asynchronously via the registered MessageListener (of type XMLMessageListener). If blocking, client applications must call one of the receive method flavours on Consumer to get the delivered message. Note that hasBlockingConsumer() is provided for convenience to let client applications know the type of Consumer instances registered with this MessageDispatchTarget.

Returns:

result

hasBlockingConsumer

boolean hasBlockingConsumer()

Returns:

result
