HTML::Mason::Resolver - Component path resolver base class
# make a subclass and use it
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
The HTML::Mason::Resolver provides a virtual parent class from which
all resolver implementations should inherit.
This class is used by most of the Mason objects 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 subclasss constructor.
HTML::Mason::Resolver is a subclass of Class::Container so you
do not need to subclass it yourself.
If you are interested in creating a resolver subclass, you must
implement the following methods.
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.
Takes three arguments: an absolute component path, a component root key,
and a component root path. Returns a new
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.
Using a Resolver with HTML::Mason::ApacheHandler
If you are creating a new resolver that you intend to use with the
HTML::Mason::ApacheHandler module, then
you must implement the following method as well.
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
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
