  • Field Details

    • INDEX_PARAMETERS

      private static final int[] INDEX_PARAMETERS
      Magic constants for faster integer division by a constant.

      This is computed as (n * scale + offset) >> (32 + shift). For a divisor n, the constants are stored as such:

      • scale at 3 * (n - 1)
      • offset at 3 * (n - 1) + 1
      • shift at 3 * (n - 1) + 2
