# 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.

  Description
  `protected List<EndpointResolver>`
  `getResolvers()`
  `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 given 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.
  `final void`
  `setBus(Bus b)`
  `void`
  `unregister(EndpointResolver resolver)`
  Unregister an endpoint resolver.

  - ### EndpointResolverRegistryImpl

    public EndpointResolverRegistryImpl(Bus b)

- ## Method Details

  - ### 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
