对面的交集在groovy集合 [英] Opposite of intersect in groovy collections

问题描述

在groovy集合中相交的对面是什么？

what would be the opposite of intersect in groovy collections?

推荐答案

您可能想要结合@Andre和@denis

You probably want to combine both the answers from @Andre and @denis

我想你想要的是联合，然后从这

I think what you want is the union and then subtract the intersection from this

def a = [1,2,3,4,5]
def b = [2,3,4]

assert [1,5] == ( a + b ) - a.intersect( b )

denis给出的解决方案将取决于是否

The solution given by denis would depend on whether you do

def opposite = leftCollection-rightCollection // [1,5]

或

def opposite = rightCollection-leftCollection // []

我不认为你想要的
