    public interface ListenerOrBuilder
    extends com.google.protobuf.MessageOrBuilder
    • Method Detail

      • getName

        java.lang.String getName()
         The unique name by which this listener is known. If no name is provided,
         Envoy will allocate an internal UUID for the listener. If the listener is to be dynamically
         updated or removed via :ref:`LDS <config_listeners_lds>` a unique name must be provided.
         
        string name = 1;
        Returns:
        The name.
      • getNameBytes

        com.google.protobuf.ByteString getNameBytes()
         The unique name by which this listener is known. If no name is provided,
         Envoy will allocate an internal UUID for the listener. If the listener is to be dynamically
         updated or removed via :ref:`LDS <config_listeners_lds>` a unique name must be provided.
         
        string name = 1;
        Returns:
        The bytes for name.
      • hasAddress

        boolean hasAddress()
         The address that the listener should listen on. In general, the address must be unique, though
         that is governed by the bind rules of the OS. E.g., multiple listeners can listen on port 0 on
         Linux as the actual port will be allocated by the OS.
         Required unless ``api_listener`` or ``listener_specifier`` is populated.

        Returns:
        Whether the address field is set.

        Address getAddress()
         The address that the listener should listen on. In general, the address must be unique, though

         Listener filters have the opportunity to manipulate and augment the connection metadata that

         :ref:`filter_chains <envoy_v3_api_field_config.listener.v3.Listener.filter_chains>`. Order matters as the
         filters are processed sequentially right after a socket has been accepted by the listener, and
         before a connection is created.
         UDP Listener filters can be specified when the protocol in the listener socket address in
         :ref:`protocol <envoy_v3_api_field_config.core.v3.SocketAddress.protocol>` is :ref:`UDP
         <envoy_v3_api_enum_value_config.core.v3.SocketAddress.Protocol.UDP>` and no

         They are processed sequentially right before connection creation. And like TCP Listener filters, they can be used to manipulate the connection metadata and socket. But the difference is that they can't be used to pause connection creation.

      • getInternalListenerOrBuilder

        Listener.InternalListenerConfigOrBuilder getInternalListenerOrBuilder()
         Used to represent an internal listener which does not listen on OSI L4 address but can be used by the
         :ref:`envoy cluster <envoy_v3_api_msg_config.cluster.v3.Cluster>` to create a user space connection to.
         The internal listener acts as a TCP listener. It supports listener filters and network filter chains.
         Upstream clusters refer to the internal listeners by their :ref:`name
         <envoy_v3_api_field_config.listener.v3.Listener.name>`. :ref:`Address
         <envoy_v3_api_field_config.listener.v3.Listener.address>` must not be set on the internal listeners.
        
         There are some limitations that are derived from the implementation. The known limitations include:
        
         * :ref:`ConnectionBalanceConfig <envoy_v3_api_msg_config.listener.v3.Listener.ConnectionBalanceConfig>` is not
         allowed because both the cluster connection and the listener connection must be owned by the same dispatcher.
         * :ref:`tcp_backlog_size <envoy_v3_api_field_config.listener.v3.Listener.tcp_backlog_size>`
         * :ref:`freebind <envoy_v3_api_field_config.listener.v3.Listener.freebind>`
         * :ref:`transparent <envoy_v3_api_field_config.listener.v3.Listener.transparent>`
         
        .envoy.config.listener.v3.Listener.InternalListenerConfig internal_listener = 27;
      • getEnableMptcp

        boolean getEnableMptcp()
         Enable MPTCP (multi-path TCP) on this listener. Clients will be allowed to establish
         MPTCP connections. Non-MPTCP clients will fall back to regular TCP.
         
        bool enable_mptcp = 30;
        Returns:
        The enableMptcp.
      • getIgnoreGlobalConnLimit

        boolean getIgnoreGlobalConnLimit()
         Whether the listener should limit connections based upon the value of
         :ref:`global_downstream_max_connections <config_overload_manager_limiting_connections>`.
         
        bool ignore_global_conn_limit = 31;
        Returns:
        The ignoreGlobalConnLimit.
      • getBypassOverloadManager

        boolean getBypassOverloadManager()
         Whether the listener bypasses configured overload manager actions.
         
        bool bypass_overload_manager = 35;
        Returns:
        The bypassOverloadManager.
