Future? Stores the result of a method call on the active object.
由于压缩需要移动和更新活动对象，因此不能并发执行。
Because compaction requires moving and updating live objects, it cannot be done concurrently.

其次，由于以下原因，活动对象从长期的角度来看对SOA特别有吸引力。
Second, active objects are especially appealing to SOA from the long-term perspective because of the following.
通过选择Axis，处理消息和使用消息来互连活动对象就变得容易多了。
By choosing Axis, it becomes much easier to process messages and interconnect active objects using messages.
这是因为，拷贝收集器不需要访问或拷贝死对象，只处理活动对象。
This is because a copying collector does not need to visit or copy dead objects, only live ones.
用于垃圾收集的标记和清扫阶段的GC暂停时间基于堆上的活动对象的数量。
The time spent in GC pauses for the mark and sweep phases of a garbage collection are based on the number of live objects on the heap.
他将活动对象定义为具有自己的控制线程(或自己为自己提供支持)的对象。
He defined active objects as objects having their own thread of control (or, self-powered).
Requester或Proxy——提供用于调用活动对象上的方法的接口。
Requester or Proxy? Provides an interface for invoking methods on an active object.
人们建议了许多对象模型来实现以活动为中心的服务，其中最有趣的是活动对象模型。
A number of object models were proposed for implementing activity-centered services, the most interesting being the active object model.
Servant——实现与请求者的接口和请求者创建的方法请求相对应的活动对象。
Servant? Implements the active object corresponding to the interface of the requester and method requests the requester creates.
当我们怀疑活动对象参与了回滚事务，我们必须显式刷新我们的活动对象。
We will have to explicitly refresh our live objects when we suspect they may have participated in a rollback transaction.
通过向元素添加指定的类来标记语义标签的根元素，其中元素是由活动对象框架指定的。
The root element of a semantic tag is marked by adding a specific class to the element, which is specified by the live object framework.
通过这种方式，此数据结构维持着一个相当复杂的活动对象集，并且以特定速率生成垃圾。
In this way, this data structure maintains a fairly complicated set of live objects as well as generates garbage at a particular rate.
选择多个对象，不工作，因为属性改变值的活动对象选择只适用于只有一个选择。
Just selecting multiple objects and changing the value does not work because the property selections apply only to the active object which is only one of those selected.
首先，有些人对活动对象究竟是什么感到混淆；基本上，四处流传着活动对象的太多不同定义。
First, some are confused as to what an active object is; basically, too many different definitions of active objects are "floating" around.
Method Request——包含诸如参数等上下文信息，并表示对活动对象的方法调用。
Method Request? Contains the context information such as parameters, and represents a method call on the active object.
个人名字使用标准hCard微格式来得到语义上的标签，因此表现的类似系统中的活动对象。
The person names are semantically tagged using the standard hCard micro format, and hence behave as live objects in the system.
