hi,
i want some explanation for following code
object sessionObj extends SessionVar[HashMap[String, Int]](
new HashMap[String, Int]
{
override def default(key: String): Int = 0
}
)
1. how object extends class in scala.?
2. are we going to create object of SessionVar class?
3. are we calling constructor of given class?
4. is it similar to java class which extends other class ,and then create
object of subclass?
I am beginner to scala and lift.
