Examples of org.mule.api.model.EntryPointResolverSet

org.mule.api.model.EntryPointResolverSet
EntryPointResolver resolves a method to call on the given service object when an event is received. This object maintains a set of Resolvers that will be used in order to resolve an entrypoint on a service object until one is found or until the set is exhausted. Note that there is a one-to-one mapping from component to EntryPointResolverSet. Each component must get a separate set with {@link org.mule.api.model.EntryPointResolver} instances that are not shared. An EntryPointResolver is allowed to cache stateand can assume the component will always be of the the same type.

     * Tests entrypoint discovery when there is more than one discoverable method
     * with MuleEventContext parameter.
