I want to combine two libraries, one requires me to extend an abstract class with methods a_1 a_2 ... a_n, b_1, b_2 ... b_m, and the other one provides two objects A and B that respectively implement methods a_i and b_i. Is there an elegant way to combine A and B? Here is what I'm currently doing:
class myClass extends abstractClass {
def a_1 = A.a_1
def a_2 = A.a_2
...
def b_1 = B.b_1
def b_2 = B.b_2
...
}
scala supports multiple inheretence through traits but a class cannot be inhereted from an object
here is an example
object Combiner {
trait A {
def a_1 = println("Hello A a_1")
def a_2 = println("Hello A a_2")
}
trait B {
def b_1 = println("Hello B b_1")
def b_2 = println("Hello B b_2")
}
}
abstract class absractClass {
def AC
}
class myClass extends absractClass with A with B {
override def AC = println("AC from myClass")
}
def main(args: Array[String]) {
var m = new myClass
m.AC
m.b_1
m.b_2
m.a_1
m.a_2
}
Something like this?
trait A {
def a_1: Int
def a_2: Int
def foo = a_1 + a_2
}
trait B {
def a_1 = 2
def a_2 = 3
}
class C extends A with B
println((new C).foo)
