  • Method Details

    • values

      public static Decoder.Type[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static Decoder.Type valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • get

      public static Decoder.Type get(int i)
      Return the data type stored at an index in this enum's declaration order.
      Parameters:
      i - the zero-based index into the Type values array
      Returns:
      the Type constant at that index

    • get

      private static Decoder.Type get(byte b)
      Returns the type described by a control byte.
      Parameters:
      b - the control byte to interpret
      Returns:
      the type and its payload size

    • fromControlByte

      public static Decoder.Type fromControlByte(int b)
      Determine the data type encoded in the leading bits of a control byte.
      Parameters:
      b - the control byte, whose top 3 bits encode the data type
      Returns:
      the type encoded in the top 3 bits of b
