      • api

        public org.forgerock.api.models.ApiDescription api​(ApiProducer<org.forgerock.api.models.ApiDescription> producer)
        Description copied from interface: Describable
        Provide the API description for the component. This method should perform the heavy-lifting of computing the API descriptor, and should be expected to be called rarely. Upstream handlers should call this method in order to compose all of their downstream API Descriptors into a single descriptor.
        Specified by:
        api in interface Describable<org.forgerock.api.models.ApiDescription,​Request>
        Parameters:
        producer - The API producer that provides general information to be built into the descriptor.
        Returns:
        The description object.
