Caveats 说明 As of Java 7, functional programming in Java can only be approximated through awkward and verbose use of anonymous classes. This is expected to change in Java 8, but Guava is currently aimed at users of Java 5 and above. 在Java7中, 只能通过笨拙且啰嗦…

Lifting Now, let's review map from another perspective. map :: (T -> R) -> [T] -> [R] accepts 2 parameters, a function f :: T -> R and a list list :: [T]. [T] is a generic type paramterized by T, it's not the same as T, but definitely shares s…

大数据.多核CPU驱动了函数式编程模式的兴起.因为函数式编程更适合多线程.复杂.安全的大型软件编程.但是,对许多有应用软件开发经验的编程者来说,函数式编程模式是一种全新的.甚至抽象的概念,可能需要很长时间的学习.积累才能完全掌握和适应.对一些不算FP编程专家的人来说,如何用他们习惯的方式来使用现成的函数式软件如Slick,Spark等可能就变得是件很迫切的事情了.设计FunDA的想法就是希望那些惯用ORM(Object Relational Mapper)开发MIS系统的编程人员们能快速轻松地使…
