Uses of BiFunction in java8.util

Methods in java8.util with parameters of type BiFunction

Modifier and Type	Method and Description
static <K,V> V	Maps.compute(java.util.Map<K,V> map, K key, BiFunction<? super K,? super V,? extends V> remappingFunction) Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).
static <K,V> V	Maps.computeIfPresent(java.util.Map<K,V> map, K key, BiFunction<? super K,? super V,? extends V> remappingFunction) If the value for the specified key is present and non-null, attempts to compute a new mapping given the key and its current mapped value.
static <K,V> V	Maps.merge(java.util.Map<K,V> map, K key, V value, BiFunction<? super V,? super V,? extends V> remappingFunction) If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value.
static <K,V> V	Maps.mergeConcurrent(java.util.concurrent.ConcurrentMap<K,V> map, K key, V value, BiFunction<? super V,? super V,? extends V> remappingFunction) If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value.
static <K,V> void	Maps.replaceAll(java.util.Map<K,V> map, BiFunction<? super K,? super V,? extends V> function) Replaces each entry's value with the result of invoking the given function on that entry until all entries have been processed or the function throws an exception.
static <K,V> void	Maps.replaceAllConcurrent(java.util.concurrent.ConcurrentMap<K,V> map, BiFunction<? super K,? super V,? extends V> function) Replaces each entry's value with the result of invoking the given function on that entry until all entries have been processed or the function throws an exception.
