Add Resource Type inheritance
-----------------------------
Key: SLING-278
URL: https://issues.apache.org/jira/browse/SLING-278
Project: Sling
Issue Type: New Feature
Components: Resource, ServletResolver
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: 2.0.0
As discussed on the dev-list [1], resource type inheritance for script/servlet
resolution should be implemented as follows:
* define an optional property sling:resourceSuperType which may take a
resource type used as
the super type of a resource type. This property is stored at the node
where the scripts
located for the resource type. (see below)
* if the sling:resourceSuperType is not set for a given resource type, any
non-mixin base type
of the primary node type of the resource node may be selected.
* the resourceSuperType of a property resource is the resourceSuperType of
the parent node
plus the property name.
* define a sling:ResourceSuperType mixin node type, which defines the
sling:resourceType
property for it to be attachable to any node.
* Add Resource.getResourceSuperType() returning the super type of the
resource type or
null if no such super type exists.
* Add support to the Servlet Resolver to resolve scripts not just for the
resource type but also
for the super type (if defined). This super type resolution takes place
before falling back
default scripts !
