java.lang.Object
- com.adaptris.core.services.aggregator.MessageAggregatorImpl
- - com.adaptris.core.json.aggregator.JsonAggregatorImpl
  - - com.adaptris.core.json.aggregator.JsonMergeAggregator

All Implemented Interfaces:

MessageAggregator
```
@ComponentProfile(summary="Merge each message into an existing JSON object.",
                  tag="json")
public class JsonMergeAggregator
extends JsonAggregatorImpl
```
MessageAggregator implementation that merges each message to a JSON object or array.
The payloads from the collection are assumed to be JSON objects, and will be aggregated into the pre-split message be it an object or array. Messages that are not JSON objects will be ignored but an error will be thrown should the pre-split message not be valid.

In the adapter configuration file this class is aliased as json-merge-aggregator which is the preferred alternative to the fully qualified classname when building your configuration.
