Marshaling results of nested tasks

Abstract

The present invention extends to methods, systems, and computer program products for marshaling results of nested tasks. Unwrap methods are used to reduce the level of task nesting and insure that appropriate results are marshaled between tasks. A proxy task is used to represent the aggregate asynchronous operation of a wrapping task and a wrapped task. The proxy task has a completion state that is at least indicative of the completion state of the aggregate asynchronous operation. The completion state of the aggregate asynchronous operation is determined and set from one or more of the completion state of the wrapping task and the wrapped task. The completion state of the proxy task can be conveyed to calling logic to indicate the completion state of the aggregate asynchronous operation to the calling logic.

Description

[0001] Cross References to Related Applications [0002] Not applicable. technical field [0003] The present invention relates to the results of nested tasks, and more particularly to the marshalling of the results of nested tasks. Background technique [0004] 1. Background and related technologies [0005] Computer systems and related technologies affect many aspects of society. Indeed, the ability of computer systems to process information has transformed the way people live and work. Computer systems now routinely perform many tasks (eg, word processing, scheduling, accounting, etc.) that were performed manually before the advent of computer systems. More recently, computer systems have been coupled to each other and to other electronic devices to form wired and wireless computer networks over which the computer systems and other electronic devices can communicate electronic data. Accordingly, the performance of many computing tasks is distributed across multiple d...

Coding such logic is non-trivial and relatively difficult if the logic takes into account exceptions, cancellations, etc.
