因此，绑定事件过滤器与事件处理程序意味着设置在特定事件发生时采取特定操作的情形。
Later, you'll define an interaction set, which will illustrate the simplest policy of an event generating an action without a filter or a delay.

In this case the Actionable event filter is a very simple filter, which just checks the value in an event field.
在本例中actionableEvent过滤器是一个非常简单的过滤器，它只检查每个事件字段的值。
When you bind an event filter to an event handler, you are creating an instance of the CIM_IndicationSubscription class and setting the properties filter and handler of that instance.
在绑定事件过滤器与事件处理程序时，您是在创建cim_indicationsubscription类的实例并设置该实例的Filter和handler属性。

除了使用以上提到的概要，用户还可以创建他们自己的过滤器并将它绑定到JNDI。
In all measurements used to generate the results above, the Actionable event filter returned true for one in every 1000 events, so one action was generated for every 1000 events processed.
在以上所有用来生成结果的度量数据中，ActionableEvent过滤器在每处理1000个事件返回1个true，因此每处理1000个事件将生成1个动作。
An event subscription contains a filter, which is a Boolean expression that evaluates to true for events it subscribes to and to false for all other events.
事件订阅包含筛选器，这是一个布尔表达式，对所订阅的事件求值为True，对其他所有事件求值为False。
