A Null Object is an object that extends a base type with a null or neutral behavior. Here’s the Scala version of the Java example Wikipedia uses to demonstrate this:

}
class NullAnimal extends Animal {
def makeSound() {}
}
As you can imagine, later in your application you might have some code like this:

Some times to understand good design, you have to see examples of what not to do. I have no idea what ESPN is thinking with this dark background and small font when their content is displayed on an iPad.
I just saw this code that shows how to declare an empty immutable SortedSet in Scala, and wanted to save it as a helpful snippet here:
/** * The node ring gossipped that contains only members that are Up. */ var nodes: immutable.SortedSet[Address] = immutable.SortedSet.empty

Today I’m sharing some examples of the Scala Option/Some/None syntax. These examples will show how to use an Option for the var fields in a Scala class. Then I’ll show how to set those Option fields, and then get the values from the Option fields.
To get started, we’ll need a little case class to represent an Address:
