Ruby

Camel supports Ruby among other Scripting Languages to allow an Expression or Predicate to be used in the DSL or Xml Configuration.

To use a Ruby expression use the following Java code

import static org.apache.camel.builder.script.ScriptBuilder.*;

...

... ruby("someRubyExpression") ...

For example you could use the ruby function to create an Predicate in a Message Filter or as an Expression for a Recipient List
