=head1 NAME

Perl::Critic::Utils::POD::ParseInteriorSequence - Pod::Parser subclass to find all interior sequences.


    use Perl::Critic::Utils::POD::ParseInteriorSequence;

    my $parser = Perl::Critic::Utils::POD::ParseInteriorSequence->new();
    my @sequences = $parser->parse_interior_sequences(
        $pod->content() );


Provides a means to extract interior sequences from POD text.


This module is considered to be private to Perl::Critic. It can be
changed or removed without notice.

=head1 METHODS


=item C<get_interior_sequences( $pod_text )>

Returns an array of all the interior sequences from a given chunk of POD
text, represented as L<Pod::InteriorSequence|Pod::InputObjects> objects.
The POD text is assumed to begin with a POD command (e.g.  C<=pod>).

=item C<interior_sequence( $seq_cmd, $seq_arg, $pod_seq )>

Overrides the parent's method of the same name. Stashes the $pod_seq
argument, which is a C<Pod::InteriorSequence> object, so that
C<get_interior_sequences()> has access to it.
