类名称：WorkItemHandler

WorkItemHandler介绍

[英]A work item handler is responsible for executing work items of a specific type. They represent the glue code between an abstract, high-level work item that is used inside the process and the implementation of this work item. Work item handlers should be registered with the WorkItemManager for each type of work that can be executed in the engine. A work item handler is responsible for executing a work item whenever the work item manager delegates one to it. It should also notify the work item manager when the work item has been completed. It is also possible that a work item handler is requested to abort an existing work item (that is still executing) because it is no longer necessary. This might for example be because the process instance (or a part of the process instance) that is was executing in is being aborted. The work item handler should then try to abort this work item (if possible) and if necessary clean up runtime state related to its execution. For example, a work item handler that is responsible for executing email work items will retrieve the necessary information from the work item (from, to, body, etc.) and invoke the mail server. Afterwards, it will notify the WorkItemManager that the work item was completed.
[中]工作项处理程序负责执行特定类型的工作项。它们表示流程内部使用的抽象、高级工作项与该工作项的实现之间的粘合代码。对于可以在引擎中执行的每种工作类型，工作项处理程序都应该向WorkItemManager注册。工作项处理程序负责在工作项经理将一个工作项委托给它时执行该工作项。当工作项完成时，还应通知工作项经理。工作项处理程序也可能因为不再需要而被请求中止现有工作项（仍在执行）。例如，这可能是因为正在中执行的流程实例（或流程实例的一部分）正在被中止。然后，工作项处理程序应尝试中止此工作项（如果可能），并在必要时清除与其执行相关的运行时状态。例如，负责执行电子邮件工作项的工作项处理程序将从工作项（从、到、正文等）检索必要的信息，并调用邮件服务器。之后，它将通知WorkItemManager工作项已完成。
