示例1: compare

@Override
public int compare(
Entry<AsyncLogger, PrepareRecoveryResponseProto> a,
Entry<AsyncLogger, PrepareRecoveryResponseProto> b) {

// A response that has data for a segment is always better than one
// that doesn't.
if (r1.hasSegmentState() != r2.hasSegmentState()) {
return Booleans.compare(r1.hasSegmentState(), r2.hasSegmentState());
}
if (!r1.hasSegmentState()) {
// Neither has a segment, so neither can be used for recover.
// Call them equal.
return 0;
}
// They both have a segment.

"%s and %s do not have the same start txid.", r1, r2);

// the finalized one is greater.

r1 + ", " + r2);
