        public abstract void intoArray​(long[] a,
                                       int a_offset,
                                       int[] indexMap,
                                       int i_offset)
        Stores this vector into an array using indexes obtained from an index map.

        For each vector lane, where N is the vector lane index, the lane element at index N is stored into the array at index a_offset + indexMap[i_offset + N].

        Parameters:
        a - the array
        a_offset - the offset into the array, may be negative if relative indexes in the index map compensate to produce a value within the array bounds
        indexMap - the index map
        i_offset - the offset into the index map
        Throws:
        IndexOutOfBoundsException - if i_offset < 0, or i_offset > indexMap.length - this.length(), or for any vector lane index N the result of a_offset + indexMap[i_offset + N] is < 0 or >= a.length

                                       int i_offset)
        Stores this vector into an array using indexes obtained from an index map and using a mask.

        For each vector lane, where N is the vector lane index, if the mask lane at index N is set then the lane element at index N is stored into the array at index a_offset + indexMap[i_offset + N].

        Parameters:
        a - the array
        a_offset - the offset into the array, may be negative if relative indexes in the index map compensate to produce a value within the array bounds
        m - the mask
        indexMap - the index map
        i_offset - the offset into the index map
        Throws:
        IndexOutOfBoundsException - if j < 0, or i_offset > indexMap.length - this.length(), or for any vector lane index N where the mask at lane N is set the result of a_offset + indexMap[i_offset + N] is < 0 or >= a.length
