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 <
