Interface Recipient

All Known Subinterfaces:

PeerableRecipient

All Known Implementing Classes:

NSObject

public interface Recipient

An interface for an object that can receive messages from the Objective-C runtime. In order to receive messages, the object should be passed to the RuntimeUtils.createProxy() method.

The NSObject class is a concrete implementation of this interface that contains all of the plumbing necessary to operate in the world of the Objective-C runtime. It is probably best to just subclass NSObject rather than implement your own Recipient class.
