Subject [jira] [Updated] (SLING-7377) Expose derived resource types for a given resource type
Date Mon, 09 Jul 2018 16:40:00 GMT

     [ https://issues.apache.org/jira/browse/SLING-7377?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konrad Windszus updated SLING-7377:
-----------------------------------
    Description: 
Currently {{sling:resourceSuperType}} properties are only evaluated in the Sling Servlet Resolver
and it is only possible to retrieve the super type of a given type (via {{Resource.getResourceSuperType()}}
(https://issues.apache.org/jira/browse/SLING-278) but not vice versa.

For the use case of e.g. searching for content of resource type {{a}} or any type derived
from {{a}} it is necessary to know all resource types derived from {{a}} (direct or transitive)
up front.

For that I propose to extend the {{ResourceResolver}} interface with an additional method
which retrieves all derived resource types for a given type.

There was an initial discussion about this in https://www.mail-archive.com/dev@sling.apache.org/msg73080.html.
