NAME

PPIx::Regexp::Util - Utility functions for PPIx::Regexp;

SYNOPSIS

use PPIx::Regexp::Util qw{ __instance };
    .
    .
    .
__instance( $foo, 'Bar' )
    or die '$foo is not a Bar';

DESCRIPTION

This module contains utility functions for PPIx::Regexp which it is convenient to centralize.

The contents of this module are private to the PPIx::Regexp package. This documentation is provided for the author's convenience only. Anything in this module is subject to change without notice. Caveat user.

This module exports nothing by default.

SUBROUTINES

This module can export the following subroutines:

__instance

__instance( $foo, 'Bar' )
    and print '$foo isa Bar', "\n";

This subroutine returns true if its first argument is an instance of the class specified by its second argument. Unlike UNIVERSAL::isa, the result is always false unless the first argument is a reference.

SEE ALSO

Params::Util, which I recommend, but in the case of PPIx::Regexp I did not want to introduce a dependency on an XS module when all I really wanted was the function of that module's _INSTANCE() subroutine.

SUPPORT

Support is by the author. Please file bug reports at http://rt.cpan.org, or in electronic mail to the author.
