Class CustomRouter
java.lang.Object
guarana.util.observer.smart.SmartObservable
guarana.framework.task.Task
guarana.toolkit.task.routers.Router
guarana.toolkit.task.routers.CustomRouter
- All Implemented Interfaces:
- ISource, guarana.util.observer.smart.ISmartObserver
public abstract class CustomRouter
- extends Router
Allows for the creation of a customised router task with a different semantics from
the predefined tasks already provided by this package. This task have just one input gateway but can have
several output.
A custom router does not change the state of inbound messages, just route them to two or more output slots!
It means the MESSAGE_ID is kept the same!
Graphical notation:
This is an Integration Pattern implementation
Problem: How do you route a message according to a particular need?
Solution: Use a custom router.
Details:
- Number of Inputs: 1
- Number of Outputs: n
- Outbound messages are built with new Java Objects!
- Since:
- Guaranį SDK 1.0.0
