All Implemented Interfaces:

Serializable, Function<CharSequence,CharSequence>, UnaryOperator<CharSequence>

public class HighMultiReplacer
extends StringReplacer

高效替换器，通过查找指定关键字，替换对应的值 基于AC自动机算法实现，需要被替换的原字符串越大，替换的键值对越多，效率提升越明显 注意: 如果需要被替换的关键字出现交叉,最先匹配中的关键字会被替换 1、"abc","ab" 会优先替换"ab" 2、"abed","be" 会优先替换"abed" 3、"abc", "ciphers" 会优先替换"abc"

Since:

Java 17+
