Examples of org.apache.camel.support.ExpressionAdapter

org.apache.camel.support.ExpressionAdapter
A helper class for developers wishing to implement an {@link org.apache.camel.Expression}using Java code with a minimum amount of code to write so that the developer only needs to implement one of the {@link #evaluate(org.apache.camel.Exchange,Class)} or{@link #evaluate(org.apache.camel.Exchange)} methods. @version
