Abstract
An event architecture facilitates the asynchronous invocation of events at an event sink. The events are triggered by direct invocation of methods on the event sink. A backchannel connection may be utilized to pass control information from an event sink to an event source. The use of the backchannel connection creates bidirectional connections between an event source and an event sink. A guardian object may be situated between the event source and the event sink to facilitate the asynchronicity of event delivery and to account for disparate threading models between the event source and the event sink. A third party connector may be utilized to connect the event source with the event sink.
