      • getVersionInfo

        public String getVersionInfo()
         The version_info provided in the request messages will be the version_info
 received with the most recent successfully processed response or empty on
 the first request. It is expected that no new request is sent after a
 response is received until the Envoy instance is ready to ACK/NACK the new
 configuration. ACK/NACK takes place by returning the new API config version
 as applied or the previous API config version respectively. Each type_url
 (see below) has an independent version associated with it.
        string version_info = 1;
        Specified by:
        getVersionInfo in interface DiscoveryRequestOrBuilder
        Returns:
        The versionInfo.

      • getVersionInfoBytes

        public com.google.protobuf.ByteString getVersionInfoBytes()
         The version_info provided in the request messages will be the version_info
 received with the most recent successfully processed response or empty on
 the first request. It is expected that no new request is sent after a
 response is received until the Envoy instance is ready to ACK/NACK the new
 configuration. ACK/NACK takes place by returning the new API config version
 as applied or the previous API config version respectively. Each type_url
 (see below) has an independent version associated with it.
        string version_info = 1;
        Specified by:
        getVersionInfoBytes in interface DiscoveryRequestOrBuilder
        Returns:
        The bytes for versionInfo.

      • hasNode

        public boolean hasNode()
         The node making the request.
        .envoy.api.v2.core.Node node = 2;
        Specified by:
        hasNode in interface DiscoveryRequestOrBuilder
        Returns:
        Whether the node field is set.

      • getResourceNamesList

        public com.google.protobuf.ProtocolStringList getResourceNamesList()
         List of resources to subscribe to, e.g. list of cluster names or a route
 configuration name. If this is empty, all resources for the API are
 returned. LDS/CDS may have empty resource_names, which will cause all
 resources for the Envoy instance to be returned. The LDS and CDS responses
 will then imply a number of resources that need to be fetched via EDS/RDS,
 which will be explicitly enumerated in resource_names.
        repeated string resource_names = 3;
        Specified by:
        getResourceNamesList in interface DiscoveryRequestOrBuilder
        Returns:
        A list containing the resourceNames.

      • getResourceNamesCount

        public int getResourceNamesCount()
         List of resources to subscribe to, e.g. list of cluster names or a route
 configuration name. If this is empty, all resources for the API are
 returned. LDS/CDS may have empty resource_names, which will cause all
 resources for the Envoy instance to be returned. The LDS and CDS responses
 will then imply a number of resources that need to be fetched via EDS/RDS,
 which will be explicitly enumerated in resource_names.
        repeated string resource_names = 3;
        Specified by:
        getResourceNamesCount in interface DiscoveryRequestOrBuilder
        Returns:
        The count of resourceNames.

      • getResourceNames

        public String getResourceNames​(int index)
         List of resources to subscribe to, e.g. list of cluster names or a route
 configuration name. If this is empty, all resources for the API are
 returned. LDS/CDS may have empty resource_names, which will cause all
 resources for the Envoy instance to be returned. The LDS and CDS responses
 will then imply a number of resources that need to be fetched via EDS/RDS,
 which will be explicitly enumerated in resource_names.
        repeated string resource_names = 3;
        Specified by:
        getResourceNames in interface DiscoveryRequestOrBuilder
        Parameters:
        index - The index of the element to return.
        Returns:
        The resourceNames at the given index.

      • getResourceNamesBytes

        public com.google.protobuf.ByteString getResourceNamesBytes​(int index)
         List of resources to subscribe to, e.g. list of cluster names or a route
 configuration name. If this is empty, all resources for the API are
 returned. LDS/CDS may have empty resource_names, which will cause all
 resources for the Envoy instance to be returned. The LDS and CDS responses
 will then imply a number of resources that need to be fetched via EDS/RDS,
 which will be explicitly enumerated in resource_names.
        repeated string resource_names = 3;
        Specified by:
        getResourceNamesBytes in interface DiscoveryRequestOrBuilder
        Parameters:
        index - The index of the value to return.
        Returns:
        The bytes of the resourceNames at the given index.

      • getTypeUrl

        public String getTypeUrl()
         Type of the resource that is being requested, e.g.
 "type.googleapis.com/envoy.api.v2.ClusterLoadAssignment". This is implicit
 in requests made via singleton xDS APIs such as CDS, LDS, etc. but is
 required for ADS.
        string type_url = 4;
        Specified by:
        getTypeUrl in interface DiscoveryRequestOrBuilder
        Returns:
        The typeUrl.

      • getResponseNonce

        public String getResponseNonce()
         nonce corresponding to DiscoveryResponse being ACK/NACKed. See above
 discussion on version_info and the DiscoveryResponse nonce comment. This
 may be empty only if 1) this is a non-persistent-stream xDS such as HTTP,
 or 2) the client has not yet accepted an update in this xDS stream (unlike
 delta, where it is populated only for new explicit ACKs).
        string response_nonce = 5;
        Specified by:
        getResponseNonce in interface DiscoveryRequestOrBuilder
        Returns:
        The responseNonce.
