NAME¶
HTML::Mason::Resolver - Component path resolver base class
VERSION¶
version 1.54
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
paremeters 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.
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 HTML::Mason::ApacheHandler.
