  • Method Details

    • size

      int size()
      Get the number of elements in this list.
      Returns:
      the element count

    • isEmpty

      boolean isEmpty()
      Check if this list is empty.
      Returns:
      true if the list has no elements

    • get

      double get(int index)
      Get an element by index.
      Parameters:
      index - the element index (0-based)
      Returns:
      the double value
      Throws:
      NullPointerException - if the element is null
      IndexOutOfBoundsException - if index is out of range

    • isNull

      boolean isNull(int index)
      Check if an element is null by index.
      Parameters:
      index - the element index (0-based)
      Returns:
      true if the element is null

    • iterator

      PrimitiveIterator.OfDouble iterator()
      Get a primitive iterator over the elements.
      Returns:
      a primitive double iterator

    • forEach

      void forEach(DoubleConsumer action)
      Perform an action for each element.
      Parameters:
      action - the action to perform

    • toArray

      double[] toArray()
      Convert to a primitive array.
      Returns:
      a new array containing all elements
