=head1 NAME

Catalyst::DispatchType - DispatchType Base Class

=head1 SYNOPSIS

See L<Catalyst>.

=head1 DESCRIPTION

This is an abstract base class for Dispatch Types. 

=head1 METHODS

=head2 $self->list($c)

abstract method, to be implemented by dispatchtypes. Called to display
info in debug log.

=cut

sub list { }

=head2 $self->match( $c, $path )

abstract method, to be implemented by dispatchtypes. Returns true if the
dispatch type matches the given path

=cut

sub match { die "Abstract method!" }

=head2 $self->register( $c, $action )

abstract method, to be implemented by dispatchtypes. Takes a
context object and a L<Catalyst::Action> object. 

Should return true if it registers something, or false otherwise.

=cut

sub register { }

=head2 $self->uri_for_action( $action, \@captures )

abstract method, to be implemented by dispatchtypes. Takes a
L<Catalyst::Action> object and an arrayref of captures, and should
return either a URI part which if placed in $c->req->path would cause
$self->match to match this action and set $c->req->captures to the supplied
arrayref, or undef if unable to do so.

=cut

sub uri_for_action { }
