We will only hack for a bit each day so show up with your questions.
In talking with David Blasby, he mentioned a couple of ideas to get
people interested in the Feature Model branch. One idea was to talk
about what has improved, and to mention successes as they are obtained.
I know that "modeling" is a dry subject best discussed over a Martini
(and if the conversation lasts over a minuet something stronger).
So instead I am going to talk about some of the other improvements that
make the Feature Model branch a joy to work on. And I miss everytime I
come back to trunk or 2.2.x.
The FeatureTypeBuilder is great! It suffers from a raw usability you
rarely fine in geotools. A before and after will suffice...
Before (use of TypeFactory):
TypeFactory f =
(TypeFactory) gt.getComponentInstanceOfType(
TypeFactory.class );
List address = new ArrayList();
address.add( attribute( "name", TEXT ));
address.add( attribute( "suite", NUMBER ));
address.add( attribute( "address", TEXT ));
ComplexType ADDRESS = f.createComplexType(
typeName("pigeon://localhost/polly","Person"),
address, true, false, null, null, null );
After (use of TypeBuilder):
ComplexTypeBuilder b =
(ComplexTypeBuilder) gt.getComponentInstanceOfType(
ComplexTypeBuilder.class );
b.setNamespaceURI("pigeon://localhost/polly");
b.setName("Address");
b.attribute("name", TEXT );
b.attribute("suite", NUMBER );
b.attribute("address", TEXT );
ComplexType ADDRESS = b.build();
In case it was not clear from the above example you can combine these
things as you do with StringBuffer (or hibernate statements):
ComplexType ADDRESS = b.setNamespaceURI("pigeon://localhost/polly").
setName("Address").attribute("name", TEXT ).attribute("suite",
NUMBER ).attribute("address", TEXT ).build();
Cheers,
Jody
