根据
Groovy 3.0 release notes
:
Groovy为现有的Java类添加了许多扩展方法。在Groovy中
3、新增了约80种此类扩展方法。我们只强调一个
这里有几个:。。。
我需要2.5.x分支中不存在的此类新方法的完整列表。我在哪里可以找到它(谷歌没有帮助我:/)?
动机
:我开发了一个
groovy extension library
我经常使用Groovy没有的方法。我即将更新它以使用Groovy 3.0.3,但我想删除Groovy中已经实现的任何方法。
由于这个问题已经结束,我将在这里为感兴趣的人回答:
答案:
我在groovy邮件列表中收到了帮助:
如果你有源代码和IDE,并搜索“@since 3.0”,当使用*Methods.java作为文件掩码搜索时,你会找到79个结果,使用*Extensions.java作为文档掩码搜索时会找到1个结果。可能有一些添加时没有@ssince,或者添加在与其他文件掩码匹配的文件中,但这是一个良好的开端。
这是我发现的:
