Consumers and Suppliers

[Bruno P. Kinoshita]

I remember talking with someone on reddit [1] about class names in Java 8, Guava, Functional Java and Apache Functor. 

Parts of this feedback were already merged into Apache Functor, and we are now discussing how to fix other issues before the first release.

Functional Java uses Effect too [2], but in Functor we call it Procedure [3]. The method names are still different (run, accept, e, etc), but we may use the same method name as Java 8 or some other already released library in Apache Functor (to help developers coming from other API's).

What I find confusing about Consumer is that the Java functional libraries that I used before (functional java and google guava) use different names. But nothing that writing a few classes wouldn't help :o)
