A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

I'm going to start off by motivating what I'm doing here. And I want to be clear that I'm not "dissing" the existing collections implementation or anything as unproductively negative as that. It was a really good experiment, it was a huge step forward given what we knew back in 2.8, but now it's time to learn from that experiment and do better. This proposal uses what I believe are the lessons we can learn about what worked, what didn't work, and what is and isn't important about collections in Scala.
This is going to start out sounding really negative and pervasively dismissive, but bear with me! There's a point to all my ranting. I want to be really clear about my motivations for the proposal being the way that it is.
この記事は Play framework Advent Calendar 2014 の7日目です。
昨日は @dorako321 さんの Play framework Advent Calendar 2014 6日目 位置情報を使ってみよう でした。
明日は @nazoking さんの play2.3 の sbt-web を使わず node で代替システムを作るための資料 です。
さて、そんなこんなで公式ドキュメントではまだ語られていない ActionFunction とそのサブトレイトについて紹介したいと思います。 (公式ドキュメントにも記載ありました https://www.playframework.com/documentation/2.3.x/ScalaActionsComposition#Different-request-types )
