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
