locate

public com.google.common.util.concurrent.ListenableFuture<ServiceLocations> locate()

Description copied from interface: ServiceLocator

Returns a future that resolves to a set of ServiceLocation. If the returned object returns true from ServiceLocations.isClosed(), it means the service has closed permanently. Otherwise, any of the returned locations in ServiceLocations.getLocations() is a viable selection. It is possible for the list of locations to be empty. This means that the service is not currently available, but also has not been closed, so it may become available at some point in the future.
