From big Data rookie to Master's journey Scala 13th speaking AOP

The original video tutorial multiple inheritance is relatively good understanding, the main AOP programming process needs to understand the following is a specific example:
Trait Action
{

def doAction
}

Trait Beforeafter extends Action
{
Abstract override Def DoAction
{
println ("Before ...")
Super.doaction
println ("After ...")
}
}
Class Dog extends Action
{
Override Def DoAction =println ("Barking ...")
}
Object TESTAOP {
def main (args:array[string]): Unit = {
Val dog = new dog with Beforeafter
Dog.doaction
}
The results of the operation are as follows:
Before ...
Barking ....
After ...
