---------------------------------------
Summary: Provide more information to extension handlers
Key: SLING-9895
URL: https://issues.apache.org/jira/browse/SLING-9895
Project: Sling
Issue Type: Improvement
Components: Feature Model
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: Feature Model 1.2.14
Extension handlers get a source and a target and are invoked to merge the
source into the target. For example if two features are aggregated, a handler
is invoked twice, the target is always the resulting feature and the source is
the first feature and then the second feature.
If an extension handler wants to act on data of the aggregated features (first
and second feature in this case), the handler does not have a clue when it is
invoked about the state.
In addition, the same handlers are also used to process a prototype feature -
in some cases processing of prototypes might be different from aggregation
