Class ProxyObject

java.lang.Object

com.sun.jna.platform.win32.COM.util.ProxyObject

All Implemented Interfaces:

IConnectionPoint, IDispatch, IRawDispatchHandle, IUnknown, InvocationHandler

public class ProxyObject
extends Object
implements InvocationHandler, IDispatch, IRawDispatchHandle, IConnectionPoint

This object acts as the invocation handler for interfaces annotated with ComInterface. It wraps all (necessary) low level COM calls and dispatches them through the COM runtime.

The caller of the methods is responsible for correct initialization of the COM runtime and appropriate thread-handling - depending on the choosen handling model.
