Nodes to perform a variety of tasks.
Use the AggregateControl, AggregateReply, and AggregateRequest nodes to collate related requests and responses. Use these nodes to generate several requests in response to one input message, to control and coordinate the responses that are received in response to those requests, and to combine the information that is provided by the responses to continue processing.
Use the Collector node to generate collections of messages and make multiple synchronous or asynchronous requests in parallel. The Collector node does not need an initial fan-out stage, and can group unrelated input messages by correlating their content. You can configure dynamic input terminals on a Collector node to receive messages from different sources. You can also configure properties on the Collector node, known as event handlers, to determine how messages are added to a message collection, and when a message collection has completed.
Use the following nodes to affect error handling and reporting:
