From scala, you can list all the methods on an object (essentially the same as pressing tab in the repl), by doing this:
List(1,2,3)
.getClass.getMethods()
You can get the full method / class list by doing the following:
List(1,2,3)
.map(
(method) => { List(method.getDeclaringClass, method.getName) }
).map(println)
Which will give you the following result, neatly sorted by the class hierarchy:
List(class scala.collection.immutable.$colon$colon, head) List(class scala.collection.immutable.$colon$colon, tail) List(class scala.collection.immutable.$colon$colon, tail) List(class
