Method

intunsignedIntersect2by2(final short[] set1, final int length1, final short[] set2, final int length2, final short[] buffer)
Intersect two sorted lists and write the result to the provided output array 
if (set1.length * 64 < set2.length) {
    return unsignedOneSidedGallopingIntersect2by2(set1, length1, set2, length2, buffer);
} else if (set2.length * 64 < set1.length) {
    return unsignedOneSidedGallopingIntersect2by2(set2, length2, set1, length1, buffer);
} else {
    return unsignedLocalIntersect2by2(set1, length1, set2, length2, buffer);
booleanunsignedIntersects(short[] set1, int length1, short[] set2, int length2)
Checks if two arrays intersect 
if ((0 == length1) || (0 == length2)) {
    return false;
int k1 = 0;
int k2 = 0;
short s1 = set1[k1];
short s2 = set2[k2];
