guarana.toolkit.task.streamdealers.compressors.Unzipper
- All Implemented Interfaces:
- ISource, guarana.util.observer.smart.ISmartObserver
public class Unzipper
- extends Compressor
Uncompress an inbound message body compressed with an specific compressor.
See guarana.toolkit.task.streamdealers.compressors package for supported compressors.
Please note that to create your own unzipper you just have to implement the ICompressor interface.
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:
Solution:
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

task to the executable task reporter, so it can be executed. In this case the task execution will consume messages
from all input slots.
Please, do not call this method by yourself.

for performance reasons.
- Specified by:
update
in interface guarana.util.observer.smart.ISmartObserver
