Just wondering what is the difference between serialized comparator vs normal
comparator given below,
the reason i am trying to understand this is how will you verify if you r using
serialized comparator during debugging if the comparator is
working or not as when you debug in eclipse it shows byte info which cannot be
understood by developers.
Here r the methods i am referring to:
/** A Comparator that compares serialized IntPair. */
public static class Comparator extends WritableComparator {
public Comparator() {
super(IntPair.class);
}
public int compare(byte[] b1, int s1, int l1,
byte[] b2, int s2, int l2) {
return compareBytes(b1, s1, l1, b2, s2, l2);
}
}
static { // register this comparator
WritableComparator.define(IntPair.class, new Comparator());
}
@Override
public int compareTo(IntPair o) {
if (first != o.first) {
return first < o.first ? -1 : 1;
} else if (second != o.second) {
return second < o.second ? -1 : 1;
} else {
return 0;
}
}
