Change subject: core: Fixing some issues at SizeConverter
......................................................................
Patch Set 2: Code-Review-1
(3 comments)
Yair, first welcome back.
Personally I didn't like the previous patch that created coverity issues in the
first place.
I think we need to remove some code from this class and hope that coverity
issues will disappear with the code.
See my comments inside.

Line 53: long toType = toUnit.getUnitWeight();
Line 54: return (size) * ((Math.pow(CONVERT_FACTOR, fromType)) /
(Math.pow(CONVERT_FACTOR, toType)));
Line 55: }
Line 56:
Line 57: public static Pair<SizeUnit, Double> autoConvert(Long size,
SizeUnit inUnit) {
What is the problem here?
Why it should be Long, in convert function we using long and everything is
perfect?
Line 58: for (Pair<Long, SizeUnit> currentUnitPair :
SizeUnit.weightToUnit) {
Line 59: if (size.longValue() / Math.pow(CONVERT_FACTOR,
currentUnitPair.getFirst() - inUnit.getUnitWeight()) >= 1) {
Line 60: return new Pair<SizeConverter.SizeUnit,
Double>(currentUnitPair.getSecond(),
Line 61: Double.valueOf(SizeConverter.convert(size,
inUnit, currentUnitPair.getSecond()).doubleValue()));
Line 61: Double.valueOf(SizeConverter.convert(size,
inUnit, currentUnitPair.getSecond()).doubleValue()));
Line 62: }
Line 63: }
Line 64: return new Pair<SizeConverter.SizeUnit,
Double>(SizeUnit.BYTES, size.doubleValue());
Line 65: }
Just casting to double will do the same job.
Line 66:
Line 67: private static class CompareUnits implements Comparator<Pair<Long,
SizeUnit>>, Serializable {
Line 68:
Line 69: /**
Line 64: return new Pair<SizeConverter.SizeUnit,
Double>(SizeUnit.BYTES, size.doubleValue());
Line 65: }
Line 66:
Line 67: private static class CompareUnits implements Comparator<Pair<Long,
SizeUnit>>, Serializable {
Line 68:
Please, replace this comparator class with the inline implementation. Its not
needed and not used outside of this class.
