Techniques to remotely access object events

Abstract

Techniques to remotely access object events are described. An apparatus may comprise a processor and a memory communicatively coupled to the processor. The memory may be operative to store a remote event bridge having a surrogate object that when executed by the processor is operative to allow an observer object for a first process to subscribe to an event of a subject object for a second process using the surrogate object. In this manner, the remote event bridge and the surrogate object operates as an interface between subject objects and observer objects without any modifications to either class of objects. Other embodiments are described and claimed.

 sending a subscription request from an observer object having an observer event handler to a subject object, the subscription request to subscribe to an object event of the subject object;   receiving an event notification from the subject object via a remote event bridge, the event notification to indicate the object event has occurred; and   responsive to receiving the event notification, sending a reply to the subject object having one or more observer event arguments.

         15 . The apparatus of  claim 14 , the processor to receive the event notification via a call to an observer event handler of an observer object from a surrogate object of the remote event bridge, wherein the surrogate object and the remote event bridge are executed by a second processor.
