Message Processors

After Mule receives a message from a Message Source, it uses one or more message processors to process the message through a flow.

Message Processors can be categorized by function as follows:

  • Components are flexible tools which perform business logic implemented in Java and other scripting languages.

  • Filters only allow certain messages to continue to be processed in a flow.

  • Routers control message flow to route, re-sequence, or split and aggregate messages in a flow.

  • Scopes wrap other messages processors so as to enable them to perform together as a group.

  • Transformers convert message payload type and data format to facilitate communication between systems.

Note: Only use message processors after a Router.
