NAME

Getopt::Long::Descriptive::Opts - object representing command line switches

VERSION

version 0.114

DESCRIPTION

This class is the base class of all $opt objects returned by Getopt::Long::Descriptive. In general, you do not want to think about this class, look at it, or alter it. Seriously, it's pretty dumb.

Every call to "describe_options" will return a object of a new subclass of this class. It will have a method for the canonical name of each option possible given the option specifications.

Method names beginning with an single underscore are public, and are named that way to avoid conflict with automatically generated methods. Methods with multiple underscores (in case you're reading the source) are private.

PERL VERSION

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.

METHODS

Achtung! All methods beginning with an underscore are experimental as of today, 2009-12-12. They are likely to be formally made permanent soon.

_specified

This method returns true if the given name was specified on the command line.

For example, if @ARGS was ""--foo --bar 10"" and "baz" is defined by a default, "_specified" will return true for foo and bar, and false for baz.

_specified_opts

This method returns an opt object in which only explicitly specified values are defined. Values which were set by defaults will appear undef.

_complete_opts

This method returns the opts object with all values, including those set by defaults. It is probably not going to be very often-used.
