varargCanConsumeNextValue

private boolean varargCanConsumeNextValue(CommandLine.Model.ArgSpec argSpec,
 String nextValue)

Returns whether the next argument can be assigned to a vararg option/positional parameter.

Usually, we stop if we encounter '--', a command, or another option. However, if end-of-options has been reached, positional parameters may consume all remaining arguments.

isOption

private boolean isOption(String arg)

Returns true if the specified arg is "--", a registered option, or potentially a clustered POSIX option. Called when parsing varargs parameters for a multi-value option. When an option is encountered, the remainder should not be interpreted as vararg elements.

Parameters:

arg - the string to determine whether it is an option or not

Returns:

true if it is an option, false otherwise
