Dirk Rudolph updated SLING-11074:
---------------------------------
Description:
Currently the ModelAdapterFactory caches a cacheable model for the requested
type only
https://github.com/apache/sling-org-apache-sling-models-impl/blob/master/src/main/java/org/apache/sling/models/impl/ModelAdapterFactory.java#L430-L432
{code}
if (result.wasSuccessful() && modelAnnotation.cache() && adaptableCache !=
null) {
adaptableCache.put(requestedType, new
SoftReference<Object>(result.getValue()));
}
{code}
However, if a model is an adapter of multiple types an instance of it can also
be returned for more than just the requested type.
Caching the model for each of its adapter types may improve the cache hit
ratio.
{code}
interface A {}
interface B {}
@Model(cache=true, adaptables=Resource.class, adapters={A.class, B.class})
class Model implements A, B {}
assertSame(givenResource.adaptTo(A.class), givenResource.adaptTo(B.class))
{code}
