NAME

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

SYNOPSIS

  # make a subclass and use it

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.

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.

METHODS

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

new

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

get_info

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

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 "glob()" function to find matching files on the filesystem.
