## org.apache.cxf.endpoint
Interface EndpointResolverRegistry

    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
`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(javax.xml.namespace.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(javax.xml.namespace.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:
    `serviceName` -
  Returns:
    the newly minted EPR if appropriate, null otherwise
