ActiveRecord会为不同的任务变量使用主键和副键，它们都是作为数据库的约束而定义的。
ActiveRecord USES primary and foreign keys for a variety of tasks, and both are defined as constraints on your database.
对于所有这些任务，您将需要一些局部变量。
如果没有为调用活动或人工任务活动提供任何输出，则不会更新流程变量。
If no output is provided for an invoke or human task activity, the process variable is not updated.
参数值正是您要在任务编辑器中输入的值，其中包括上下文变量。
The parameter value is exactly the value you would enter in the task editor, including context variables.
此变量对所有具有升级的任务类型可用。
This variable is available for all task kinds with escalations.
并不是所有上下文变量的值在任务或升级生命周期中始终都可用。
Not all the values of context variables are always available during the task or escalation lifecycle.
在流程中，任务将使用一个变量在它们之间传递信息。
The tasks in the process will use a variable to pass information between them.
有了变量和任务，您就可以轻松计算了，例如计算查询进行的次数。
With variables and assignments, you can also perform easy calculations, such as counting the occurrences of a query.
此变量对所有任务类型可用。
此变量对所有具有升级的任务可用。
This variable is available for all tasks that have escalations.
您可以选择性地使用一个事件处理程序来在运行时修改任务角色变量。
Optionally, you can use an event handler to modify the task role variables at runtime.
所有其他任务必须访问流程变量。
基于人工任务或业务流程上下文的变量定义人员查询。
Define staff queries based on variables from the human task or business process context.
这里我们尝试得到一个包含了给定任务上报次数的流程变量。
Here we are trying to get a process variable, containing the count of escalation for a given task.
此变量仅对发起任务可用。
在对业务流程建模时，请确保在调用人工任务之前初始化流程变量。
When modeling the business process, make sure that the variable initialization happens prior to the human task invocation.
由于执行了所有这些非变量任务，所以您可将此映像保存到您的私有目录中。
Because all of the invariant tasks are executed you can save this image in your private catalog.
观察点是流程(任务、子流程、变量及循环)中的一些位置，在此需要测量以使KPI生效。
Observation points are the points in a process (tasks, subprocesses, variables, and loops) where measurements are needed to validate the KPI.
智能完成任务非常有效，实时过滤成员方法和变量以匹配你输入的表达式。
Smart Completion works at the right-hand side of assignments, filtering the list of methods and variables to match the expected type of expression.
变量任务需要有参数，因此最好对其进行参数化。
A variant task is one that requires parameters and therefore is best handled with parameterization.
下图显示了一个分配行为如何通过复制变量的信息部分将任务的输出信息复制到后续任务的输入端。
The figure below shows how an Assign activity copies the output of one task to the input of a subsequent task by copying the message parts of variables.
那个变量就是到程序代码的句柄，用来创建SPE任务。
That variable is the handle to the program code, which will be used to create your SPE tasks.
TDT自动识别变量和任务并建立匹配的动作。
The TDT automatically recognizes changes in variables and assignments and creates test actions to match.
非变量任务不需要参数(比如请求操作系统实例)；这可通过简单的静态方式来完成。
An invariant task is one that doesn't require parameters (like requesting an operating system instance); this one can be done with the easy static way.
此变量在任务创建之后可用。
对于能够访问业务流程上下文的内联人工任务，还有附加的上下文变量可用。
For inline human tasks that have access to the business process context, additional context variables are available.
如果Domino已经崩溃，并且不能重启，那么从Notes . ini变量Servertask删除任务，并试图缩小范围和识别导致崩溃的任务。
If Domino has crashed and is not able to restart, remove tasks from the Notes.ini variable Servertask and attempt to narrow down and identify the task causing the crash.
GPars还定义通过线程池(比如actors)调度的逻辑数据流任务并通过数据流变量进行传输。
GPars also defines logical dataflow tasks that are scheduled over a thread pool (like actors) and communicate via dataflow variables.
第1步。识别变量或非变量任务。
