MatcherRule
适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版
大多数匹配器使用对 MatcherRule 的引用，它由两个元素组成
- 用于替换匹配名称的正则表达式替换表达式。
- 转换指令，允许指定如何转换结果名称。
转换指令
支持以下转换指令
-
AS_IS：保持数据库名称不变，例如MY_name=>MY_name -
LOWER：将数据库名称转换为小写，例如MY_name=>my_name -
LOWER_FIRST_LETTER：将首字母转换为小写，例如MY_name=>mY_name -
UPPER：将数据库名称转换为大写，例如MY_name=>MY_NAME -
UPPER_FIRST_LETTER：将首字母转换为大写，例如my_NAME=>My_NAME -
CAMEL：将数据库名称转换为驼峰式命名，例如MY_name=>myName -
PASCAL：将数据库名称转换为帕斯卡式命名，例如MY_name=>MyName
示例：向名称添加前缀/后缀

一如既往，当使用正则表达式时，它们是具有默认标志的正则表达式。

换句话说，MatcherRule 描述了如何根据对象的输入名称声明和引用特定的对象类型名称（例如，表示生成的 org.jooq.Schema 的类名）。
