最佳Java函数库:JGA，公用函数，芒果还是...? [英] Best Java Functor lib: JGA, commons functor, mango, or...?

问题描述

我对在Java中使用函子(函数对象)感兴趣.通过快速搜索，我发现了以下3个程序包:

I am interested in using functors (function objects) in Java. With quick googling I found these 3 packages:

• Java泛型算法: http://jga.sourceforge.net/
• 公用函子: http://commons.apache.org/sandbox/functor/
• 芒果: http://www.jezuk.co.uk/cgi- bin/view/mango

• Java Generics Algorithms: http://jga.sourceforge.net/
• Commons functor: http://commons.apache.org/sandbox/functor/
• Mango: http://www.jezuk.co.uk/cgi-bin/view/mango

在3个方面，JGA似乎拥有最好的设计.但是我怀疑这里实际使用过一个或多个软件包的其他人也许能够提供关于这些(也许其他)函子软件包的优缺点的更多见识.

and of 3, JGA seemed like it might have the best design. But I suspect others here who have actually used one or more of the packages might be able to offer more insight as to pros and cons of these (and perhaps other) functor packages.

推荐答案

Google馆藏库提供一个相似的Function接口(尽管深度可能不一样).

The Google Collections Library provides a Function interface that is similar (though probably not as in depth).
