using new keyword with def instead of classname

[Taimoor Hasnie]

Hi,

I cant understand this code. Can somebody help me with understanding this please. Here is the link to the entire snippet http://code.google.com/p/orient/wiki/ScalaLanguage

object Test {

        implicit def dbWrapper(db: ODatabaseObjectTx) = new {

                def queryBySql[T](sql: String, params: AnyRef*): List[T] = {

                        val params4java = params.toArray

                        val results: java.util.List[T] = db.query(new OSQLSynchQuery[T](sql), params4java: _*)

                        results.asScala.toList

                }
        }

Q1. I havent seen the use of 'new' keyword like this.  What is new keyword achieving here? I have usually seen the usage like new SomeClass . Where new creates a new object for the mentioned classname. But here we have function...and this is confusing me.

Thanks,

Taimoor.

Here is is creating an anonymous class -- just like in Java.

With the disadvantage that calls to queryBySql() will be dispatched using reflection, because the inferred return type of that method will be a structural one. (just sayin’)

Also, he's using the 'pimp my library' pattern to effectively add the queryBySql method to ODatabaseObjectTX class. See here for more info:
