What is the proxy object?

Proxy Objects act as an intermediary between an accessible object and the client. Proxy Objects monitors the lifespan of the accessible objects and forwards the calls to the objects when it is not destroyed. Proxy objects check the availability of accessible objects whenever a client calls an IAccessible property to know proper information about the object.

The proxy object passes the requests of the client to the accessible object. When an accessible object is not present or is destroyed, an error is returned by the proxy object. The proxy object is always clear to the client.
