/**
 * Returns the next endpoint to route a message to or null to finish routing.
 * This implementation leverages Camel's
 * <a href="http://camel.apache.org/bean-integration.html">Bean injection</a>
 * to pass parts of the Camel Exchange to the method for processing. This can
 * help the code be easier to maintain as it does not need the extra boilerplate
 * code for extracting the relative data from the Exchange.
 * <p></p>
 * This implementation stores an int property with the message exchange that is
 * used to drive the routing behavior. This method will be called from multiple
 * threads, one per message, so storing message specific state as a property is
 * a good strategy.
 *
 * @param body       the IN message converted to a String using Camel Bean injection
 * @param properties the properties map associated with the Camel Exchange
 * @return next endpoint uri(s) to route to or <tt>null</tt> to finish routing
