Question

In addition to this question Find number range intersection I want to get the intersection range of 2 time ranges. So my question is

What is the efficient mathematical/algorithmic way to get the time range of the intersection of two number ranges ?

Answer 1

    public BTraceStatsTimeRange getOverlap(BTraceStatsTimeRange other) {
    if (!intersect(other)) {
        return NULL;
    }
    long startOther = other.start;
    long endOther = other.end;
    long minEnd = Math.min(end, endOther);
    long maxStart = Math.max(start, startOther);
    return new BTraceStatsTimeRange(Math.min(minEnd, maxStart), Math.max(
            minEnd, maxStart));
}

I am tired today …. 😉
