Description

GeoTool's lack of support for parsing XML into complex features limits its effectiveness as a GIS toolkit. I propose to add this functionality by modifying currently existing Simple-feature-only type hierarchies and creating new classes to handle complex types, some of which follow:

• WFSContentDataAccess
• WFSDataAccessFactory
• XmlComplexFeatureParser
• AttributeBuilder
• ComplexFeatureBuilder

**TODO: add diagrams of before and after type hierarchies.

The XmlComplexFeatureParser is one of the key components, it uses the AttributeBuilder and ComplexFeatureBuilder to create objects that reflect the content of the XML responses (to GetFeature requests).

The WFSContentDataAccess, WFSDataAccessFactory and their parent types have been created and modified respectively to reflect the current simple feature access API as much as possible. [See examples {link:below}]
