Interface AdapterManager

@ProviderType
public interface AdapterManager

The AdapterManager defines the service interface for a manager for object adaption. The adapter manager coordinates the registered AdapterFactory services on behalf of clients wishing to adapt objects to other types. One such client is the SlingAdaptable class, which uses the implementation of this bundle to adapt "itself".

Clients may either extend from the SlingAdaptable class or access the AdapterManager service from the OSGi service registry to adapt objects to other types.

This interface is not intended to be implemented by clients.
