org.activemq.filter
Class DestinationMap  

java.lang.Object
  org.activemq.filter.DestinationMap

---

public class DestinationMap

extends java.lang.Object

A Map-like data structure allowing values to be indexed by org.activemq.message.ActiveMQDestination and retrieved by destination - supporting both * and > style of wildcard as well as composite destinations.
This class assumes that the index changes rarely but that fast lookup into the index is required. So this class maintains a pre-calculated index for destination steps. So looking up the values for "TEST.*" or "*.TEST" will be pretty fast.
Looking up of a value could return a single value or a List of matching values if a wildcard or composite destination is used.
