Examples with Adaptable org.apache.sling.api.adapter.Adaptable used on opensource projects

Example 1 with Adaptable

use of org.apache.sling.api.adapter.Adaptable in project sling by apache.

the class ModelAdapterFactory method adapt.

     * @param value the object from which to adapt
     * @param type the target type
     * @param isWithinCollection
     * @return a Result either encapsulating an exception or the adapted value
