  - ### Method Detail

    - #### values

          public static ServerLauncher.Command[] 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 (ServerLauncher.Command c : ServerLauncher.Command.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static ServerLauncher.Command 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

    - #### isCommand

          public static boolean isCommand(java.lang.String name)

      Determines whether the specified name refers to a valid Server launcher command, as defined by this enumerated type.
      Parameters:
        `name` - a String value indicating the potential name of a Server launcher command.
      Returns:
        a boolean indicating whether the specified name for a Server launcher command is valid.

    - #### isUnspecified

          public static boolean isUnspecified(ServerLauncher.Command command)

      Determines whether the given Server launcher command has been properly specified. The command is deemed unspecified if the reference is null or the Command is UNSPECIFIED.
      Parameters:
        `command` - the Server launcher command.
      Returns:
        a boolean value indicating whether the Server launcher command is unspecified.
      See Also:
        `UNSPECIFIED`

    - #### valueOfName

          public static ServerLauncher.Command valueOfName(java.lang.String name)

      Looks up a Server launcher command by name. The equality comparison on name is case-insensitive.
      Parameters:
        `name` - a String value indicating the name of the Server launcher command.
      Returns:
        an enumerated type representing the command name or null if the no such command with the specified name exists.

    - #### getName

          public java.lang.String getName()

      Gets the name of the Server launcher command.
      Returns:
        a String value indicating the name of the Server launcher command.

    - #### getOptions

          public java.util.List<java.lang.String> getOptions()

      Gets a set of valid options that can be used with the Server launcher command when used from the command-line.
      Returns:
        a Set of Strings indicating the names of the options available to the Server launcher command.

    - #### hasOption

          public boolean hasOption(java.lang.String option)

      Determines whether this Server launcher command has the specified command-line option.
      Parameters:
        `option` - a String indicating the name of the command-line option to this command.

        a boolean value indicating whether this command has the specified named command-line option.

    - #### isUnspecified

          public boolean isUnspecified()

      Convenience method for determining whether this is the UNSPECIFIED Server launcher command.
      Returns:
        a boolean indicating if this command is UNSPECIFIED.
      See Also:
        `UNSPECIFIED`

    - #### toString

          public java.lang.String toString()

      Gets the String representation of this Server launcher command.
