@Override
public int compare(AttrValue o1, AttrValue o2)
{
Long ts1 = o1.getEffectiveSequenceNumber(); // ??
Long ts2 = o2.getEffectiveSequenceNumber(); // ??
return ts1.compareTo(ts2);
}
Would you expect a measureable impact of creating these
variables ts1, ts2, instead of "inlining" the calls to
getEffectiveSequenceNumber(). (Using JDK 6?)
How can I reason about this things, probably influenced by
JIT, without doing actually measurements, say as part of a
code inspection?
