                        int length)
        Description copied from class: AbstractDoubleList
        Add (hopefully quickly) elements to this type-specific list.

        This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

        Specified by:
        addElements in interface DoubleList
        Overrides:
        addElements in class AbstractDoubleList
        Parameters:
        index - the index at which to add elements.
        a - the array containing the elements.
        offset - the offset of the first element to add.
        length - the number of elements to add.

      • setElements

        public void setElements​(double[] a)
        Description copied from interface: DoubleList
        Set (hopefully quickly) elements to match the array given.
        Specified by:
        setElements in interface DoubleList
        Parameters:
        a - the array containing the elements.

      • setElements

        public void setElements​(int index,
                        double[] a)
        Description copied from interface: DoubleList
        Set (hopefully quickly) elements to match the array given.
        Specified by:
        setElements in interface DoubleList
        Parameters:
        index - the index at which to start setting elements.
        a - the array containing the elements.

      • setElements

        public void setElements​(int index,
                        double[] a,
                        int offset,
                        int length)
        Description copied from interface: DoubleList
        Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by 
         ListIterator iter = listIterator(index);
 int i = 0;
 while (i < length) {
   iter.next();
   iter.set(a[offset + i++]);
 }
        However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

        Overrides:
        setElements in class AbstractDoubleList
        Parameters:
        index - the index at which to start setting elements.
        a - the array containing the elements
        offset - the offset of the first element to add.
        length - the number of elements to add.

      • size

      • size

        public void size​(int size)
        Description copied from interface: DoubleList
        Sets the size of this list.

        If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

        Specified by:
        size in interface DoubleList
        Overrides:
        size in class AbstractDoubleList
        Parameters:
        size - the new size.
