Description

Please see the associated proposal:

http://docs.codehaus.org/display/GEOTOOLS/ComplexFeature+Parsing+and+Building+Support

GeoTool's lack of support for parsing XML into complex features limits its utility as a GIS toolkit.

I propose to add this functionality by augmenting the codebase such that there are complex-compatible analogues or alternatives to all the classes necessary for WFS-based communications. Existing type hierarchies will be modifed and added to to provide this new functionality. In making these changes I will strive for maximum reuse of existing code and will follow the coding patterns and API conventions currently employed; as such, the code for performing a complex feature request will be much like the code for a simple feature request. Breaking changes will be eschewed.

Central to this work is a new XmlComplexFeatureParser which will use an AttributeBuilder and a ComplexFeatureBuilder to create objects that represent the content of WFS XML responses.

Hi Andrea,

I have been finalising and tidying up my work on this which is being stored here:
https://github.com/Adam-Brown/geotools/commits/master

There are some tests which may be of interest to you:
XmlComplexFeatureParserTest
ComplexFeatureBuilderTest
FeatureWrapperTest

The XmlComplexFeatureParser can handle local xlinks (i.e. those starting with #). The FeatureWrapper is an optional utility that allows you to define strongly typed POJOs to map to a Feature. The feature wrapper can then use reflection to 'wrap' a Feature in a strongly-typed object.

I've tried to make the comments in the code as lucid as possible but please let me know if there are any problems or you need more information.
