--------------------------------------------------------------------------------------------

                 Key: CAMEL-1048
                 URL: https://issues.apache.org/activemq/browse/CAMEL-1048
             Project: Apache Camel
          Issue Type: New Feature
            Reporter: James Strachan
             Fix For: 2.0.0


For example we may want to do this route...

{code}
<route>
  <requires>
    <el>${broker2.queueSize('AnotherQueue') == 0}</el>
  </requires>
  <from uri="broker1:MyQueue"/>
  <to uri="broker2:AnotherQueue"/>
</route>
{code}

i.e. only implement a specific route while some predicate is true (e.g. only route while a condition is met; disable when its not met).
