Java – how to add @ serialVersionUID to an anonymous class?

I want to translate the following code from Java to scala:

Foo foo = new Foo() { private static final long serialVersionUID = 12345L; }

Foo class is an abstract class

What about the equivalent code in scala?

Solution

There is a Scala annotation for adding the ID. however, it seems that you cannot apply this solution to anonymous inner classes However, according to the scala FAQ:

code

object Ser extends Application {
    trait Foo { def xy: Int }
    val x = new Foo with java.io.Serializable { def xy = 2; private val serialVersionUID = 1L }
}

Use 2.8 The compiler compiles well I haven't tested it yet, although the serial version of the result class is actually provided
