Enterprise Integration Pattern Reference
Table of Contents
- Route Editor Patterns
- Endpoints
- Endpoint — Act as either a message source or a message sink
- Bean — Binds a bean to Camel message exchanges
- Log — Creates log messages using the Simple language
- Process — Process the message using a custom processor
- Routing
- Aggregate — Aggregates many messages into a single message
- Choice — Routes messages based on a series of predicates
- Dynamic Router — Routes messages based on rules specified by the recipients at start up
- Filter — Filters messages before passing them to a resource
- Idempotent Consumer — Filters out duplicate messages
- Load Balance — Balances message processing among a number of nodes
- Multicast — Routes a message to a number of endpoints
- Otherwise — Route to be executed when all other choices evaluate to false
- Pipeline — Executes a sequence of processors in order
- Recipient List — Routes messages to a number of dynamically specified recipients
- Resequence — Resequences messages based on an expression
- Routing Slip — Routes a message through a series of steps that are determined at runtime
- Sort — Sorts the contents of the message
- Split — Sorts the contents of the message
- When — Triggers a route when an expression evaluates to true
- Wire Tap — Routes a copy of a message to a secondary destination while passing the original
message to the actual recipient, or it creates a new message and passes that to the
recipient.
- Control Flow
- Catch — Catches exceptions as part of a try, catch, finally block
- Delay — Delays processing for a specified length of time
- Finally — Node traversed when a try, catch, finally block exits
- Intercept — Intercepts a message at each step in the route
- Intercept From — Intercepts incoming messages
- Intercept Send To Endpoint — Intercepts messages sent to an endpoint
- Loop — Processes a message multiple times
- On Completion — Route to be executed when normal route processing completes
- On Exception — Route to be executed when an exception is thrown
- Rollback — Forces a rollback of a route
- Throttle — Controls the rate at which messages are passed to the next node in the route
- Throw Exception — Throws an exception
- Transacted — Marks a route as a transaction
- Try — Marks the beginning of a Try, Catch, Finally block
- Transformation
- Convert Body — Converts the message body to a form usable by the next endpoint
- Enrich — Enriches a message with data from a secondary resource
- In Only — Marks the exchange pattern for the route to one way (Event Message pattern)
- In Out — Marks the exchange pattern for the route to request/reply
- Marshal — Marshals data into a specified format for transmission over a transport or
component
- Poll Enrich — Enriches messages with data retrieved from a polling consumer
- Remove Header — Removes a named header from the message
- Remove Headers — Removes message headers whose name matches a specified pattern
- Remove Property — Removes a named property from the message exchange
- Set Body — Sets the contents of the message body
- Set Exchange Pattern — Sets the exchange pattern for the route
- Set Fault Body — Sets the contents of a fault message's body
- Set Header — Sets the value of a message header
- Set Out Header — Sets the value of a header on the outbound message
- Set Property — Sets a named property on the message exchange
- Transform — Transforms the message based on an expression
- Unmarshal — Converts the message data received from the wire into a format that Apache Camel
processors can consume
- Miscellaneous
- AOP — Does processing before and/or after the route is completed
- Policy — Defines a policy the route will use
- Sampling — Extract a sample of the exchanges passing through a route
- Stop — Stops the processing of the current message
- Threads — Specifies that all steps after this node are processed asynchronously
- Validate — Validates a message based on an expression
