      • max

        public static <T extends java.lang.Comparable<T>> CollectConsumer<T,​java.util.Optional<T>> max()
        Return a collector that return the max value in sequence as Result. If sequence is empty, will return empty Optional
        类型参数:
        T - the element type

      • min

        public static <T extends java.lang.Comparable<T>> CollectConsumer<T,​java.util.Optional<T>> min()
        Return a collector that return the min value in sequence as Result. If sequence is empty, will return empty Optional
        类型参数:
        T - the element type

      • toMap

        public static <K,​V> CollectConsumer<java.util.Map.Entry<K,​V>,​java.util.Map<K,​V>> toMap​(java.util.function.Supplier<java.util.Map<K,​V>> mapSupplier)
        Collect entry Sequence to Map.
        参数:
        mapSupplier - to provider the map

      • toHashMap

        public static <K,​V> CollectConsumer<java.util.Map.Entry<K,​V>,​java.util.Map<K,​V>> toHashMap()
        Collect entry Sequence to HashMap.

      • toImmutableMap

        public static <K,​V> CollectConsumer<java.util.Map.Entry<K,​V>,​java.util.Map<K,​V>> toImmutableMap()
        Collect entry Sequence to immutable map.
