- Method Detail
  - createPolicy
```
DocumentProtocolRoutingPolicy createPolicy(java.lang.String param)
```
    This method creates and returns a routing policy that corresponds to the implementing class, using the given parameter string. There is only ever one instance of a routing policy for a given name and parameter combination, and because of this the policies must be stateless beyond what can be derived from the parameter string. Because there is only a single thread running route resolution within message bus, it is not necessary to make policies thread-safe. For more information see RoutingPolicy. Do NOT throw exceptions out of this method because that will cause the running thread to die, just return null to signal failure instead.
    
    Parameters:
    
    param - The parameter to use when creating the policy.
    
    Returns:
    
    The created routing policy.
  - destroy
```
void destroy()
```
    Destroys this factory and frees up any resources it has held. Making further calls on a destroyed factory causes a runtime exception.
