use of com.vmware.photon.controller.model.util.ServiceEndpointLocator in project photon-model by vmware.

the class EndpointAdapterUtils method registerEndpointAdapters.

/**
 * Register end-point adapters into End-point Adapters Registry.
 *
 * @param host
 *         The host the end-point is running on.
 * @param endpointType
 *         The type of the end-point.
 * @param startedAdapterLinks
 *         The array of started adapter links.
 * @param adapterLinksToRegister
 *         Map of adapter links (to be registered) to their adapter type key. e.g for
 *         standard adapters this is {@link com.vmware.photon.controller.model.UriPaths.AdapterTypePath#key}
 * @param registryLocator
 *         ServiceEndpointLocator containing the host of the adapter registry. Can be null if the
 *         registry is on the same host.
 * @see #handleEndpointRegistration(ServiceHost, EndpointType, Consumer, ServiceEndpointLocator)
