EXPOSING ASYNCHRONOUS MECHANISMS AS FIRST-CLASS EVENTS
Conversions can be applied to various asynchronous and/or concurrent mechanisms. In particular, such mechanism can be transformed into first-class events to facilitate processing with respect to first-class events including but not limited to querying. Both conventional events and asynchronous computations can be transformed to these events, for example by generating and linking a proxy event thereto.
1 . A system that facilitates asynchronous processing, comprising:
a component that acquires an asynchronous computation; and
a conversion component that converts the computation into a first-class event.
2 . The system of claim 1 , the asynchronous computation is an event that adheres to a non-first-class design pattern.
3 . The system of claim 1 , the conversion component exposes a mechanism to facilitate termination of the asynchronous computation.
4 . The system of claim 1 , the conversion component employs one or more extension methods to convert the computation.
5 . The system of claim 1 , the conversion component employs reflection to convert the computation.
6 . The system of claim 1 , the asynchronous computation is implemented in accordance with a BeginInvoke/EndInvoke pattern.
7 . The system of claim 1 , the asynchronous computation is implemented according to a continuation passing style.
8 . The system of claim 1 , the conversion component generates and links a proxy event to the operation to produce the first-class event.
9 . The system of claim 1 , one or both of the components form part of a code rewriter or generation system.
10 . The system of claim 1 , where the first-class event enables adding handlers for success, failure, and termination.
11 . A method of exposing operations as first-class events, comprising:
identifying an asynchronous or concurrent operation; and
transforming the operation into a first-class event by generating and linking a proxy event to the operation.
12 . The method of claim 11 , further comprising converting from add and remove functions to an add method that returns a remove function.
13 . The method of claim 11 , further comprising ignoring a sender parameter associated with the operation.
14 . The method of claim 11 , comprising transforming the operation with one or more extension methods.
15 . The method of claim 11 , comprising employing reflection to transform the operation.
16 . The method of claim 11 , comprising identifying an operation of a BeginInvoke/EndInvoke pattern.
17 . The method of claim 11 , comprising identifying an operation of a continuation passing style.
18 . The method of claim 11 , comprising identifying an operation of a virtual method or futures pattern.
19 . A method of converting operations to first-class events, comprising:
identifying a blocking operation; and
converting the blocking operation into a non-blocking first-class event.
20 . The method of claim 19 , further comprising applying the conversion from blocking to non-blocking operation to convert a synchronous function to asynchronous function.
