ServerConfiguration
public interface SocketConfiguration
The SocketConfiguration configures a port to listen on and its associated server socket parameters.

  • Field Details

    • DEFAULT

      @Deprecated static final SocketConfiguration DEFAULT
      Deprecated.
      since 2.0.0 This configuration does not contain a name and will be removed
      The default socket configuration.

    • DEFAULT_BACKLOG_SIZE

      static final int DEFAULT_BACKLOG_SIZE
      The default backlog size to configure the server sockets with if no other value is provided.

  • Method Details

    • name

      default String name()
      Name of this socket. Default to WebServer.DEFAULT_SOCKET_NAME for the main and default server socket. All other sockets must be named.
      Returns:
      name of this socket

    • port

      int port()
      Returns a server port to listen on with the server socket. If port is 0 then any available ephemeral port will be used.
      Returns:
      the server port of the server socket

    • bindAddress

      InetAddress bindAddress()
      Returns local address where the server listens on with the server socket. If null then listens an all local addresses.
      Returns:
      an address to bind with the server socket; null for all local addresses

    • backlog

      int backlog()
      Returns a maximum length of the queue of incoming connections on the server socket.

      Default value is DEFAULT_BACKLOG_SIZE.

      Returns:
      a maximum length of the queue of incoming connections

    • timeoutMillis

      int timeoutMillis()
      Returns a server socket timeout in milliseconds or 0 for an infinite timeout.
      Returns:
      a server socket timeout in milliseconds or 0

    • receiveBufferSize

      int receiveBufferSize()
      Returns proposed value of the TCP receive window that is advertised to the remote peer on the server socket.

      If 0 then use implementation default.

      Returns:
      a buffer size in bytes of the server socket or 0

    • tls

      Optional<WebServerTls> tls()
      Return a WebServerTls containing server TLS configuration. When empty Optional is returned no TLS should be configured.
      Returns:
      web server tls configuration

    • ssl

      @Deprecated(since="2.3.1", forRemoval=true) SSLContext ssl()
      Deprecated, for removal: This API element is subject to removal in a future version.
      use tls().sslContext() instead. This method will be removed at 3.0.0 version.
      Returns a SSLContext to use with the server socket. If not null then the server enforces an SSL communication.

      use tls().enabledTlsProtocols() instead. This method will be removed at 3.0.0 version.
      Returns the SSL protocols to enable, or null to enable the default protocols.
      Returns:
      the SSL protocols to enable

    • allowedCipherSuite
