The idea is that adapters for objects are accessed based on the actual type of an object. These adapters supply additional functionality. The adapters are located using an StrategyRegistry.
The lookup of adapters is based on an inheritance search; thus providing an adapter for type java.util.Map will match any object that implements the Map interface. The inheritance search works its way up the class hierarchy looking for a matching registration. If nothing is found, then all the interfaces directly or indirectly implemented by the selector class are checked. java.lang.Object is always the final match.

As a special case, the value null is search for as if it was an instance of the class void.
The StrategyBuilder service creates a service implementation around a strategy registry.
