Folks (especially Jody),
I know this is more of a GeoTools 2.6 question, but...
I wanted to sort a FeatureCollection, hence I wrote something like:
FilterFactory filterFactory = CommonFactoryFinder
.getFilterFactory(null);
SortByImpl sort = (SortByImpl) filterFactory.sort(
BulletinIngestor.NAMECOLUMN, SortOrder.ASCENDING);
SubFeatureList outList = new SubFeatureList(outColl, sort);
Iterator<SimpleFeature> featIter = (Iterator<SimpleFeature>) outList
.openIterator();
But the last line gave me an NPE...
I investigated a bit, and it turned out that openIterator() eventually called
createIndex(), which in turn called getFeatureMember(), which relies on the
index
member variable, which is created by createIndex() !
So, unless I got it wrong, I presume there is something flawed in
SubFeatureList,
since it relies on the sorted List to produce the sorted List instead on
relying
the un-sorted Collection.
I solved the issue by subclassing SubFeatureList and overriding
getFeatureMember:
shall I open an issue and attach a patch to solve the problem directly within
SubFeatureList ?
