Groovy在地图中查找元素索引

Question

我有以下Groovy地图,

def mymap=["TXT_TXT":1,"IMG_TXT":2,"TXT_IMG":3,"IMG_IMG":4]

如何在此地图中找到元素的索引？

Answer 1

使用findIndexOf方法如下:

def mymap=["TXT_TXT":1,"IMG_TXT":2,"TXT_IMG":3,"IMG_IMG":4]

assert 3 == mymap.findIndexOf{it.key=="IMG_IMG"}

assert 0 == mymap.findIndexOf{it.value==1}
