Ref Expression Language

Available as of Camel 2.8

The Ref Expression Language is really just a way to lookup a custom Expression from the Registry.
This is particular useable in XML DSLs.

Example usage

The Splitter in XML DSL can utilize a custom expression using <ref> like:

<bean id="myExpression" class="com.mycompany.MyCustomExpression"/>


  <from uri="seda:a"/>
    <to uri="mock:b"/>

in this case, the Message coming from the seda:a Endpoint will be splitted using a custom Expression which has the id myExpression in the Registry.

And the same example using Java DSL:



The Constant language is part of camel-core.
