@Language("bean")
public class BeanLanguage
extends org.apache.camel.support.TypedLanguageSupport
implements org.apache.camel.spi.ScriptingLanguage, org.apache.camel.spi.PropertyConfigurer, org.apache.camel.StaticService

A bean language which uses a simple text notation to invoke methods on beans to evaluate predicates or expressions

The notation is essentially beanName.methodName which is then invoked using the beanName to lookup in the <a href="http://camel.apache.org/registry.html>registry then the method is invoked to evaluate the expression using the bean integration to bind the Exchange to the method arguments.

As of Camel 1.5 the bean language also supports invoking a provided bean by its classname or the bean itself.
