6 HTML::Mason::Resolver - Component path resolver base class
7
9 # make a subclass and use it
10
12 The resolver is responsible for translating a component path like
13 /foo/index.html into a component. By default, Mason expects components
14 to be stored on the filesystem, and uses the
15 HTML::Mason::Resolver::File class to get information on these
16 components.
17
18 The HTML::Mason::Resolver provides a virtual parent class from which
19 all resolver implementations should inherit.
20
22 This class is used by most of the Mason object's to manage constructor
23 parameters and has-a relationships with other objects.
24
25 See the documentation on this class for details on how to declare what
26 parameters are valid for your subclass's constructor.
27
28 HTML::Mason::Resolver is a subclass of Class::Container so you do not
29 need to subclass it yourself.
30
32 If you are interested in creating a resolver subclass, you must
33 implement the following methods.
34
35 new This method is optional. The new method included in this class is
36 simply inherited from "Class::Container". If you need something
37 more complicated done in your new method you will need to override
38 it in your subclass.
39
40 get_info
41 Takes three arguments: an absolute component path, a component root
42 key, and a component root path. Returns a new
43 HTML::Mason::ComponentSource object.
44
45 glob_path
46 Takes two arguments: a path glob pattern, something like "/foo/*"
47 or "/foo/*/bar", and a component root path. Returns a list of
48 component paths for components which match this glob pattern.
49
50 For example, the filesystem resolver simply appends this pattern to
51 the component root path and calls the Perl "glob()" function to
52 find matching files on the filesystem.
53
54 Using a Resolver with HTML::Mason::ApacheHandler
55 If you are creating a new resolver that you intend to use with the
56 HTML::Mason::ApacheHandler module, then you must implement the
57 following method as well.
58
59 apache_request_to_comp_path ($r, @comp_root_array)
60 This method, given an Apache object and a list of component root
61 pairs, should return a component path or undef if none exists.
62 This method is used by the HTML::Mason::ApacheHandler class to
63 translate web requests into component paths. You can omit this
64 method if your resolver subclass will never be used in conjunction
65 with HTML::Mason::ApacheHandler.
