Recommended ways to pass functions

[Kevin Jung]

Hi all,
I read 'Passing Functions to Spark' section in Spark Programming Guide.
It recommends make function Anonymous or static to avoid transfer whole
class instance.
So, I wonder if I can pass functions like this.

case1: define func2 inside func1
class{
  def func1() = {
    def func2() = {...}
    rdd.map(x=> func2())
  }
}

case2: define inner object
class{
  def func1() = {
    rdd.map(x=>MyFunc.func2())
  }

  object MyFunc{
    def func2() = {...}
  }
}

Thanks in advance.

Kevin
