public class MergedMultiResource
extends SyntheticResource

MergedMultiResource is a synthetic resource that presents a merged view on multiple resources. This is done by providing a ValueMap in adaptTo(Class) that merges the values of all resources, ie. provide a null value for a key if the value is not the same in all resurces and only present a value if that one is present in exactly all of the resources.
