13.7.2. Aggregator
| Class | org.jboss.soa.esb.actions.Aggregator |
This is a message aggregation action. It is an implementation of the aggregator enterprise integration pattern. (see http://www.enterpriseintegrationpatterns.com/Aggregator.html.)
This action relies on all messages having the correct correlation data. This data is set on the message as a property called "aggregatorTag" (Message.Properties). See the ContentBasedRouter and StaticRouter actions.
The data has the following format:
[UUID] ":" [message-number] ":" [message-count]
If all the messages have been received by the aggregator, it returns a new Message containing all the messages as part of the Message.Attachment list (unnamed), otherwise the action returns null.
| Property | Description | Required |
|---|---|---|
| timeoutInMillis |
Timeout time in milliseconds before the aggregation process times out.
| No |
