Modifier and Type	Method and Description
static <K,V> V	computeIfAbsent(Map<K,V> map, K key, Function<K,V> mappingFunction) Use this method instead if Map.computeIfAbsent(Object, Function) when the mapping functions are recursive and/or will end up accessing the same map again.

Method Detail

computeIfAbsent

public static <K,V> V computeIfAbsent(Map<K,V> map,
                                      K key,
                                      Function<K,V> mappingFunction)

Use this method instead if Map.computeIfAbsent(Object, Function) when the mapping functions are recursive and/or will end up accessing the same map again. This is necessary because starting with JDK9 Map.computeIfAbsent(Object, Function) throws ConcurrentModificationException if used in concurrent, recursive, or nested fashion.
