Getting value from nested map in groovy using a nested key

Question

Suppose I have nested map like this

def someMap = [
   a : [
      b : [
         c : "value",
         d : "anothervalue"
      ]
   ]
]

I get the key at runtime as a string. Say it is "a.b.c"

How can I pull the value out of the map?

I know I can do myMap.a.b.c but for me, "a.b.c" is single string, I found out about at runtime?

Thanks

You could just go down the nodes likes this and try to get the respective child:

def key = "a.b.c"
def entry = someMap
key.split('\.').each { entry = entry?.get(it) }
println entry?.value
