Java NIO2をScalaでラップするやつ(findだけ)
import java.nio.file.{Path, Files => JFiles}
import java.nio.file.attribute.BasicFileAttributes
import java.util.function.{BiPredicate, Consumer}
import scala.collection.JavaConverters._
object Files {
import JFunction._
def find(path: Path, depth: Int = Int.MaxValue)(matcher: (Path, BasicFileAttributes) => Boolean): Iterator[Path] =
JFiles.find(path, depth, matcher.asJava).iterator().asScala
object JFunction {
implicit class BiPredicateAsJava[A, B](val biPred: (A, B) => Boolean) {
def asJava: BiPredicate[A, B] = new BiPredicate[A, B] {
override def test(a: A, b: B): Boolean = biPred(a, b)
implicit class ConsumerAsJava[A](val consumer: A => Unit) {
def asJava: Consumer[A] = new Consumer[A] {
override def accept(a: A): Unit = consumer(a)
