## 目的
|
|
给定一种语言，请定义其语法的表示形式，以及使用该表示形式来解释该语言中的句子的解释器。
|

## 适用性
|
|
有一种要解释的语言时，请使用解释器模式，并且可以将语言中的语句表示为抽象语法树。解释器模式在以下情况下效果最佳
|
|
|
|
* 语法很简单。 对于复杂的语法，语法的类层次结构变得庞大且难以管理。 在这种情况下，解析器生成器之类的工具是更好的选择。 他们可以在不构建抽象语法树的情况下解释表达式，这可以节省空间并可能节省时间
|
|
* 效率不是关键问题。 通常，最有效的解释器不是通过直接解释解析树来实现的，而是先将其转换为另一种形式。 例如，正则表达式通常会转换为状态机。 但是即使这样，翻译器也可以通过解释器模式实现，因此该模式仍然适用。
