Hello:
I am just learning how to use GeoTools, and have been working with an
example file someone sent me. The file had some runtime issues, so I've
been rewriting it and in the process, found some documentation errors:
FeatureResults.collection() refers to a way to the following:
*public* FeatureCollection collection() *throws* IOException {
FeatureCollection collection = FeatureCollections.newCollection()
*for* (FeatureReader r = reader(); r.hasNext();) {
collection.add( r.next() );
}
*return* collection; }
This would not compile for me, and I found the following issues while
researching it:
FeatureResults.reader() suggests using FeatureCollections.features()
which doesn't exists. It should be FeatureCollection.features(), which
returns a FeatureIterator, not a FeatureReader as referred to in the
original example. With all this in mind, I rewrote the original example
to be:
public FeatureCollection myCollection() throws IOException {
FeatureCollection collection = FeatureCollections.newCollection();
FeatureIterator iterator = collection.features();
while (iterator.hasNext()) {
collection.add( iterator.next() );
}
return collection;
}
I believe this is correct, and will update files where necessary if you
concur.
Best regards,
Amy Johnson
