Thanks for the reply Jody.
But how can I tell the parse() method to use one implementation instead of
another?
I see the Parser's constructor can take a Configuration object, which seems to use PicoContainer and
have a registerBindings() method... Is that the way to configure which implementation of the
FeatureCollection I want it to use?
Can you provide a small code example?

There are several FeatureCollection implementations for different purposes. The
DefaultFeatureCollection implementation is built around a TreeMap and sorts the contents by
FeatureId.
See the docs for alternatives:

I use org.geotools.xml.Parser#parse(...) to parse a GML based XML file.
This XML contains a
<gml:FeatureCollection> which contains multiple <gml:featureMember>.
The problem is that the resulting DefaultFeatureCollection doesn't seem to
keep the order in which
the featureMembers are declared.
For example,
----------------------
Iterator<SimpleFeature> iterator = defaultFeatureCollection.iterator();
----------------------
... returns an Iterator with the elements in another order. I think
DefaultFeatureCollection
uses a
TreeMap to keep the elements, but sort them by internal ID, not by the
order they appear in
the XML.
Our application would require the order of the featureMembers to be kept...
Is there a way to
achieve this?
The only way I currently think of is to manually modify the generated
DefaultFeatureCollection
after
GeoTools has parsed the XML file.
The highest version of GeoTools I can use is 11.2 since our application
uses Java 6.
Thanks in advance!
