EA&UML日拱一卒-活动图::14.1 Summary

英文原文来自UML2.5,作者提供中文翻译。

The StateMachines package defines a set of concepts that can be used for modeling discrete event-driven Behaviors using a finite state-machine formalism. In addition to expressing the Behavior of parts of a system (e.g., the Behavior of Classifier instances), state machines can also be used to express the valid interaction sequences, called protocols, for parts of a system. These two kinds of StateMachines are referred to as behavior state machines and protocol state machines respectively.

状态机包定义了一组概念,通过这些概念可以以有限状态机体系对离散事件驱动行为进行建模。除了可以表达系统的某些部分的行为(例如,类目实例的行为)以外,状态机也可用于表达有效的交互序列,即系统中所谓协议的部分。这两种状态机分别成为行为状态机和协议状态机。

The specific form of finite state automata used in UML is based on an object-oriented variant of David Harel’s statecharts formalism. (However, readers who are familiar with that formalism should note that there is a small number of semantic differences that distinguish the UML version from the original.)

UML中使用的有限状态自动机的特定形式是基于David Harel状态图体系的一个面向对象版变体。(然而,熟悉那个体系的读者应该可以注意到UML版本和原始版本有少量的语义上的不同。)
