Groovy：如果有条件则添加根闭包

Question

A little bit confuse about this simple use case :
I want to add a closure around an other one only with conditions.
For the moment, I only succeed to do this :

if(condition) {
  my_root_closure {
    my_main_closure {
      do_stuff()
    }
  }
} else {
  my_main_closure {
    do_stuff()
  }
}

I would like to do this without repeat the my_main_closure bloc.

Answer 1

To avoid repetition, you could create new closure that calls my_main_closure and store it in a variable:

def mmc = {
    my_main_closure {
        do_stuff()
    }
}

if(condition) {
    my_root_closure( mmc )
} else {
    mmc()
}
