EndpointResolverRegistry (Apache CXF JavaDoc 4.2.2 API)
Description: declaration: package: org.apache.cxf.endpoint, interface: EndpointResolverRegistry

Package org.apache.cxf.endpoint

# 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.

  Modifier and Type
  Method
  Description
  `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.
  `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 gievn physical EPR.
  `void`
  `register(EndpointResolver resolver)`
  Register an endpoint resolver.
  `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.
  `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.
  `void`
  `unregister(EndpointResolver resolver)`
  Unregister an endpoint resolver.

- ## Method Details

  - ### 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

    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).

    Parameters:
      `logical` - the abstract EPR to resolve

  - ### renew

    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.

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

  - ### mint

    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.
    Parameters:
      `serviceName` -
    Returns:
      the newly minted EPR if appropriate, null otherwise

  - ### mint

    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 gievn physical EPR.
    Parameters:
      `physical` -
    Returns:
      the newly minted EPR if appropriate, null otherwise
