GroovyのtraitとCompileStaticとの関係

Groovyのtraitでimplementsする側に@CompileStaticをつけた場合に、trait由来のコードに@CompileStaticの効果が出るのか気になったので、groovyConsoleのFinalizationのバイトコードを確認してみた。

結論として、CallSiteとか使われなくなるし、「効率的なバイトコードになってる」ようなんだけど、ちょっとまだよくわかってない。

trait側のint型へのキャストを無くしたバージョンでMyTraitに@CompileStaticをつけると、型チェック違反でコンパイルエラーになるんだけど(期待通り)、 MyTraitじゃなくてMyClass側に@CompileStaticをつけた場合、型チェック違反にはならなかった。 なのに、効率的なコードになるというのどういうことなのかしら。 実行時エラーのリスクは低減できないけど、実行効率は良い、みたいな感じ？

サンプルコード

適当です。

import groovy.transform.CompileStatic

//@CompileStatic
trait MyTrait {
    int hoge(Object obj) {
        return ((int) obj) + 1234
        //return obj + 1234
    }
}

//@CompileStatic
class MyClass implements MyTrait {
    def fooMethod(String target){ // この辺、CompileStatic効果の出るコードってなんだっけ？と思ってググって見つけたきょんくんのコードをコピペしました
      def result = target * 3
      result.contains("G*")
    }
}

assert new MyClass().hoge(123) == 1357
