类名称：Alphabet

Alphabet介绍

[英]Class implementing an (indexed) alphabet. An alphabet is a collection of symbols, where each symbol has a (unique) index. Apart from serving as a collection, this class also provides a one-to-one mapping between symbols and indices.
[中]实现（索引）字母表的类。字母表是符号的集合，其中每个符号都有一个（唯一的）索引。除了用作集合之外，此类还提供符号和索引之间的一对一映射。
