=head1 NAME

HTML::Mason::Resolver - Component path resolver base class

=head1 SYNOPSIS

# make a subclass and use it

=head1 DESCRIPTION

The resolver is responsible for translating a component path like
/foo/index.html into a component.  By default, Mason expects
components to be stored on the filesystem, and uses the
HTML::Mason::Resolver::File class to get information on these
components.

The HTML::Mason::Resolver provides a virtual parent class from which
all resolver implementations should inherit.

=head1 Class::Container

This class is used by most of the Mason object's to manage constructor
parameters and has-a relationships with other objects.

See the documentation on this class for details on how to declare what
parameters are valid for your subclass's constructor.

HTML::Mason::Resolver is a subclass of Class::Container so you
do not need to subclass it yourself.

=head1 METHODS

If you are interested in creating a resolver subclass, you must
implement the following methods.

=over 4

=item new

This method is optional.  The new method included in this class is
simply inherited from C<Class::Container>.
If you need something more complicated done in your new method you
will need to override it in your subclass.

=item get_info

Takes three arguments: an absolute component path, a component root key,
and a component root path. Returns a new
L<HTML::Mason::ComponentSource|HTML::Mason::ComponentSource> object.

=item glob_path

Takes two arguments: a path glob pattern, something
like "/foo/*" or "/foo/*/bar", and a component root path. Returns
a list of component paths for components which match this glob pattern.

For example, the filesystem resolver simply appends this pattern to
the component root path and calls the Perl C<glob()> function to
find matching files on the filesystem.

=back

=head2 Using a Resolver with HTML::Mason::ApacheHandler

If you are creating a new resolver that you intend to use with the
L<HTML::Mason::ApacheHandler|HTML::Mason::ApacheHandler> module, then
you must implement the following method as well.

=over 4

=item apache_request_to_comp_path ($r, @comp_root_array)

This method, given an Apache object and a list of component root pairs,
should return a component path or undef if none exists.
This method is used by the
L<HTML::Mason::ApacheHandler|HTML::Mason::ApacheHandler> class to
translate web requests into component paths.  You can omit this method
if your resolver subclass will never be used in conjunction with
L<HTML::Mason::ApacheHandler|HTML::Mason::ApacheHandler>.
