public class EndpointResolverRegistryImpl extends Object implements EndpointResolverRegistry
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.

EndpointReferenceType |
mint(EndpointReferenceType physical)
Walk the list of registered EndpointResolvers, so as to mint a new
abstract EPR for a given 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.

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).

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.
