Method Detail

getOrCreate

public static <K,V> V getOrCreate(java.util.Map<K,V> map,
                                  K key,
                                  java.util.function.Supplier<V> valueCreator)

Returns:

existing value of `key` from `map`. If value doesn't exist yet for `key` yet, then `valueCreator` is used to create new value, which is then assigned to `key` and returned

getOrCreate

public static <K,V> V getOrCreate(java.util.Map<K,V> map,
                                  K key,
                                  java.util.function.Supplier<V> valueCreator,
                                  java.util.function.Consumer<V> initializer)

Parameters:

initializer - is called immediately after the value is added to the map

Returns:

existing value of `key` from `map`. If value doesn't exist yet for `key` yet, then `valueCreator` is used to create new value, which is then assigned to `key` and returned
