  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<NegotiationType>
    @ExperimentalApi("https://github.com/grpc/grpc-java/issues/1784")
public enum NegotiationType
extends java.lang.Enum<NegotiationType>
    Identifies the negotiation used for starting up HTTP/2.

      Enum Constants 
      Enum Constant Description
      PLAINTEXT
      Just assume the connection is plaintext (non-SSL) and the remote endpoint supports HTTP/2 directly without an upgrade.
      PLAINTEXT_UPGRADE
      Use the HTTP UPGRADE protocol for a plaintext (non-SSL) upgrade from HTTP/1.1 to HTTP/2.
      TLS
      Uses TLS ALPN/NPN negotiation, assumes an SSL connection.

    • Method Detail

      • values

        public static NegotiationType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (NegotiationType c : NegotiationType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static NegotiationType valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
