Consice Java Maps in Scala

This post is a follow up to my previous post on using Closure Templates in Scala.

One of the things that bugged me in the Scala example was how verbose it was compared to the Groovy version. So I had an idea - use YAML and the snakeyaml library to generate a Java Map with my data. While it's still a couple lines longer than the Groovy version, it's a lot simpler than the Scala original.

The biggest change is this:

val y = """widget: {
name: Widget Name,
display: {
  width: 240,
  height: 320
}
}"""

val yaml = new Yaml()
val map = yaml.load(y).asInstanceOf[java.util.Map[String, _]]
