Subject [jira] [Commented] (SLING-6652) Allow multiple adapters for Models with resourceType binding
Date Thu, 16 Mar 2017 10:20:42 GMT

    [ https://issues.apache.org/jira/browse/SLING-6652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15927784#comment-15927784
] 

Konrad Windszus commented on SLING-6652:
----------------------------------------

Registering multiple models on the same adapter is already supported via http://sling.apache.org/documentation/bundles/models.html#specifying-an-alternate-adapter-class-since-110.
Maybe the same implementation picker can be used if multiple resource-type-based model registrations
exist. The default implementation picker will always pick the implementation with the class
name which comes first in an alphabetical order (https://github.com/apache/sling/blob/trunk/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/FirstImplementationPicker.java).

> According to http://svn.apache.org/viewvc/sling/trunk/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/AdapterImplementations.java?view=markup#l59
the AdapterImplementations support only mapping resourceType to Adapter 1:1. I would like
to propose extending that to support 1:n binding between resourceType and adapter classes.
> My use case: 
> Lets assume I want to combine my models with the exporter framework to export 2 representations
of a single resource:
> * metadata
> * data
> To do so I would create 2 models, each bound to the same resourceType but annotated to
be exported for different selectors.
