Interface LongIterable

    • Method Detail

      • longIterator

        LongIterator longIterator()
        Returns a primitive iterator that can be used to iterate over the LongIterable in an imperative style.
      • toArray

        long[] toArray()
        Converts the LongIterable to a primitive long array.
      • toArray

        default long[] toArray​(long[] target)
        Converts the LongIterable to a primitive long array. If the collection fits into the provided array it is used to store its elements and is returned from the method, otherwise a new array of the appropriate size is allocated and returned. If the iterable is empty, the target array is returned unchanged.
      • contains

        Returns true if the value is contained in the LongIterable, and false if it is not.
      • containsAll

        default boolean containsAll​(long... source)
        Returns true if all of the values specified in the source array are contained in the LongIterable, and false if they are not.
      • containsAll

        default boolean containsAny​(long... source)
        Returns true if any of the values specified in the source array are contained in the LongIterable, and false if they are not.

        Since:
        11.0
      • containsNone

        default boolean containsNone​(long... source)

        Returns a new LongIterable with all of the elements in the LongIterable that return false for the specified predicate.
      • collect

        <V> RichIterable<V> collect​(LongToObjectFunction<? extends V> function)
        Returns a new collection with the results of applying the specified function on each element of the source collection. This method is also commonly called transform or map.
