## Interface EndpointResolverRegistry

- All Known Implementing Classes:
    EndpointResolverRegistryImpl

      public interface EndpointResolverRegistry

  Implementations of this interface are 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.

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `EndpointReferenceType` | `mint(EndpointReferenceType physical)` Walk the list of registered EndpointResolvers, so as to mint a new abstract EPR for a gievn physical EPR.
    `EndpointReferenceType` | `mint(QName serviceName)` Walk the list of registered EndpointResolvers, so as to mint a new abstract EPR for a given service name.
    `void` | `register(EndpointResolver resolver)` Register an endpoint resolver.
    `EndpointReferenceType` | `renew(EndpointReferenceType logical, 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.
    `EndpointReferenceType` | `resolve(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.
    `void` | `unregister(EndpointResolver resolver)` Unregister an endpoint resolver.

- - ### Method Detail

    - #### register

          void register(EndpointResolver resolver)

      Register an endpoint resolver.
      Parameters:
        `resolver` - the EndpointResolver to add to the chain.

    - #### unregister

          void unregister(EndpointResolver resolver)

      Unregister an endpoint resolver.
      Parameters:
        `resolver` - the EndpointResolver to remove from the chain.

    - #### resolve

          EndpointReferenceType resolve(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).

      Parameters:
        `logical` - the abstract EPR to resolve

    - #### renew

          EndpointReferenceType renew(EndpointReferenceType logical,
                                    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.

      Parameters:
        `logical` - the previously resolved abstract EPR
        `physical` - the concrete EPR to refresh
      Returns:
        the renewed concrete EPR if appropriate, null otherwise

    - #### mint

          EndpointReferenceType mint(QName serviceName)

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

    - #### mint

          EndpointReferenceType mint(EndpointReferenceType physical)

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