It is filled in by the business state machine from the operation and made available to the conditions and actions associated with the operation.
它由业务状态机从操作中填入，并用于与该操作相关的条件和操作。
From the design and practice perspective, the first thing that needs to be determined is how the business state machine and human task will interact.
从设计和实践的角度来看，需要确定的第一件事是业务状态机与人工任务如何进行交互。
A business state machine is a special type of business process because it is event driven, and its actions depend on the current state of the process.
业务状态机是一种特殊的业务流程类型，因为它是事件驱动的，其操作取决于流程当前的状态。
This would mean the business state machine is between states and thus would not be able to accept other operations, such as a request to cancel the order.
这意味着业务状态机始终处于两种状态之间，因此无法接受诸如请求取消订单之类的其他操作。
The business state machine will invoke a BPEL process, which will include an inline human task activity (why this needs to be inline will be discussed later).
业务状态机调用BPEL过程，该过程包括一个内嵌的人工任务活动（为什么需要将人工任务活动内嵌到该过程中将在下文讨论）。
A business state machine is another programming metaphor that a business analyst can create with graphical tools, yet executes in a process choreography engine.
业务状态机(business state machine)是业务分析师可以通过图形工具创建流程的另一个编程框架，并且在流程设计引擎中执行。
Whether you are creating a BPEL process, a business state machine, or any of several other types of components, you need to define custom expressions and behavior.
无论您正在创建一个BPEL过程，还是一个业务状态机，或者是几种其他类型组件中的任意一种，您都需要定义自定义表达式和行为。
As with most WebSphere Integration Developer components, authoring a business state machine means defining both its interface (or interfaces) and its implementation.

In this way the business state machine can initiate the human task during one of its operations and then, via a callback, process the approval decision from the human task.
这样，业务状态机便可以在它的某个操作过程中启动人工任务，然后通过回调处理来自人工任务的approval决定。
