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, resequence, 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.
