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.
These can transform, filter, enrich, and otherwise process the message as it transitions through your flow.
Message Processors can be categorized by function as follows:
-
Connectors send and receive data, and plug into external data sources via standard protocols or third-party APIs.
-
Components are flexible tools which perform business logic implemented in Java, Javascript, Groovy, Python, or Ruby.
-
Filters only allow certain messages to continue to be processed in a flow based on certain criteria.
-
Routers control message flow to route, resequence, or split and aggregate messages in a flow.
-
Scopes wrap snippets of code to define fine-grained behavior within a flow.
-
Transformers convert message payload type and data format to facilitate communication between systems.
-
Exception Strategies handle any errors that occur during message processing.
-
Business Events capture data related to key performance indicators.
Note: Only use message processors after a Router.
