NAME

WWW::Kontent::Foundation - Abstract base classes for Kontent

SYNOPSIS

        use WWW::Kontent::Fondation;
        
        #A store might do this:
        class MySavedPage is WWW::Kontent::SavedPage { ... }
        class MyDraftRev  is WWW::Kontent::DraftRevision { ... }
        
        # Similarly:
        role MyClass is WWW::Kontent::Class { ... }             #eventually--curently a class, not a role
        class MyRenderer is WWW::Kontent::Renderer { ... } 

DESCRIPTION

WWW::Kontent::Foundation contains abstract bases for several important classes and roles. It also pulls in WWW::Kontent::Store, which defines the six classes needed to represent pages and revisions; see that module for more niformation on those classes.

WWW::Kontent::Renderer

This base class represents a page renderer. Renderers have only one method, render, which takes a request object and returns the page's content; it is also expected to set the request object's type attribute to an appropriate value. In addition, WWW::Kontent::Renderer has a public revision attribute containing the revision that should be rendered; this attribute is managed by WWW::Kontent::Renderer and WWW::Kontent::Request for the benefit of the renderer.

WWW::Kontent::Class

This is the base class of a Kontent page class. It contains a revision attribute containing the revision whose class this is; this attribute is managed by WWW::Kontent::Class and WWW::Kontent::Request for the benefit of the page class.

Page classes must implement three methods, driver, adapter, and modelist; see "WWW::Kontent::Revision" for information on their signatures and use. They may additionally implement the methods resolve and create; the default implementations dispatch to the page object's default_resolve and default_create methods, respectively. It's very common for a page class to capture the return value from this base class's create method and set some attributes, usually the kontent:class attribute.

To avoid a rather annoying Pugs bug, the five methods currently have an underscore appended to their names; that is, they're named driver_ and so on.
