Interface HandlerHost

public interface HandlerHost

Host that dispatches transfers to registered handlers in a bulk manner, i.e., if the targeted object is registered, and any of the types to be handled are supported by a transfer, all registered types' data will be resolved and handed to the handler for further processing.

The host provides special treatments to different kind of targets:

• If the target is a gadget object, programmatic transfers will be possible.
• If the target is a graphical component, it will be registered for drop operations.
