=head1 NAME
Test::Valgrind::Util - Utility routines for Test::Valgrind.
=head1 VERSION
Version 1.18
=cut
our $VERSION = '1.18';
=head1 DESCRIPTION
This module contains some helpers used by Test::Valgrind.
It is not really designed to be used anywhere else.
=head1 FUNCTIONS
=head2 C<validate_subclass>
my ($validated_type, $error_msg) = validate_subclass($type);
Try to interpret C<$type> as a subclass of the caller package, and load it if its C<@ISA> is empty.
Returns the validated type, or C<undef> and the relevant error message.
=cut
sub validate_subclass {
my ($type) = @_;
my $base = (caller 0)[0];
$type =~ s/[^A-Za-z0-9_:]//g;
$type = "${base}::$type" if $type !~ /::/;
my $stash = do { no strict 'refs'; \%{"${type}::"} };
my $ISA = ($stash && $stash->{ISA}) ? *{$stash->{ISA}}{ARRAY} : undef;
unless ($ISA and @$ISA >= 1) {
local $@;
eval "require $type; 1" or return (undef, "Could not load subclass: $@");
}
return (undef, "$type is not a subclass of $base") unless $type->isa($base);
return $type;
}
