guarana.toolkit.task.mappers.XML2Stream
- All Implemented Interfaces:
- ISource, guarana.util.observer.smart.ISmartObserver
public abstract class XML2Stream
- extends Mapper
Maps an inbound message body from XML format to stream format.
This task does not add or remove content from the inbound messages, it keeps all the original content.
For this reason the outbound message has the same MESSAGE_ID the inbound message has.
Graphical notation:
This is an Integration Pattern implementation
Problem: How do you map messages with structured data into messages with unstructured?
Solution: Use an xml two stream mapper to map the body in xml format to stream format.
Details:
- Number of Inputs: 1
- Number of Outputs: 1
- Java Object of the inbound message is reused for the outbound message!
- Since:
- Guaranį SDK 1.0.0
