mergeBy
inline fun <K, V1 : W, V2 : W, W> mergeBy(map1: Map<out K, V1>, map2: Map<out K, V2>, resolve: (key: K, value1: V1, value2: V2) -> W): Map<K, W>
Merges the first map and the second map resolving conflicts with resolve lambda.
Precisely, corresponding keys and values of the received maps are put into a new empty map which is returned after afterwards. For every key appearing in both maps corresponding value is a result of the resolve lambda calculated on the key and its corresponding values from the merged maps.
Return
the result of the merge.
Parameters
map1
the first map to merge.
map2
the second map to merge.
resolve
lambda function that resolves merge conflicts.
