Package org.apache.cxf.bus.managers

## Class EndpointResolverRegistryImpl

- java.lang.Object
- - org.apache.cxf.bus.managers.EndpointResolverRegistryImpl

- All Implemented Interfaces:
    `EndpointResolverRegistry`

      public class EndpointResolverRegistryImpl
      extends Object
      implements EndpointResolverRegistry

  This implementation class is responsible for mediating access to registered EndpointResolvers, which themselves map between abstract and concrete endpoint references, and/or facilitate renewal of stale references.

  An underlying mechanism in the style of the OGSA WS-Naming specification is assumed, where an EPR maybe be fully abstract, or concrete but with sufficient information embedded to enable its renewal if necessary.

    `org.apache.cxf.ws.addressing.EndpointReferenceType` | `mint​(QName serviceName)` | Walk the list of registered EndpointResolvers, so as to mint a new abstract EPR for a given service name.

    - #### EndpointResolverRegistryImpl

          public EndpointResolverRegistryImpl()

    - #### EndpointResolverRegistryImpl

          public EndpointResolverRegistryImpl​(Bus b)

  - ### Method Detail

    - #### setBus

          public final void setBus​(Bus b)

      Parameters:
        `b` - Bus to encapsulate

    - #### register

          public void register​(EndpointResolver resolver)

      Register an endpoint resolver.
      Specified by:
        `register` in interface `EndpointResolverRegistry`
      Parameters:
        `resolver` - the EndpointResolver to add to the chain.

    - #### unregister

          public void unregister​(EndpointResolver resolver)

      Unregister an endpoint resolver.
      Specified by:
        `unregister` in interface `EndpointResolverRegistry`
      Parameters:
        `resolver` - the EndpointResolver to remove from the chain.

    - #### resolve

          public org.apache.cxf.ws.addressing.EndpointReferenceType resolve​(org.apache.cxf.ws.addressing.EndpointReferenceType logical)

      Walk the list of registered EndpointResolvers, so as to retrieve a concrete EPR corresponding to the given abstract EPR, returning a cached reference if already resolved.

      This API is used by any actor that requires a concrete EPR (e.g. a transport-level Conduit), and must be called each and every time the EPR content is to be accessed (e.g. before each connection establishment attempt).

      Specified by:
        `resolve` in interface `EndpointResolverRegistry`
      Parameters:
        `logical` - the abstract EPR to resolve
      Returns:
        the resolved concrete EPR if appropriate, null otherwise

    - #### renew

          public org.apache.cxf.ws.addressing.EndpointReferenceType renew​(org.apache.cxf.ws.addressing.EndpointReferenceType logical,
                                                                          org.apache.cxf.ws.addressing.EndpointReferenceType physical)

      Walk the list of registered EndpointResolvers, so as to force a fresh resolution of the given abstract EPR, discarding any previously cached reference.

      This API may be used by say the transport-level Conduit when it detects a non-transient error on the outgoing connection, or by any other actor in the dispatch with the ability to infer server-side unavailability.

      Specified by:
        `renew` in interface `EndpointResolverRegistry`
      Parameters:
        `logical` - the previously resolved abstract EPR
        `physical` - the concrete EPR to refresh
      Returns:
        the renewed concrete EPR if appropriate, null otherwise

    - #### mint

          public org.apache.cxf.ws.addressing.EndpointReferenceType mint​(QName serviceName)

      Walk the list of registered EndpointResolvers, so as to mint a new abstract EPR for a given service name.
      Specified by:
        `mint` in interface `EndpointResolverRegistry`
      Parameters:
        `serviceName` -
      Returns:
        the newly minted EPR if appropriate, null otherwise

    - #### mint

          public org.apache.cxf.ws.addressing.EndpointReferenceType mint​(org.apache.cxf.ws.addressing.EndpointReferenceType physical)

      Walk the list of registered EndpointResolvers, so as to mint a new abstract EPR for a given physical EPR.
      Specified by:
        `mint` in interface `EndpointResolverRegistry`
      Parameters:
        `physical` -
      Returns:
        the newly minted EPR if appropriate, null otherwise

    - #### getResolvers

          protected List<EndpointResolver> getResolvers()

      Returns:
        the encapsulated list of registered resolvers
