Hi Jody,
I think the ideas proposed are excellent, they are exactly what I need.
Just one more thing.
There needs to be some way to get the namespace context out of the
propertyname, too.
One of the issues I came across, was that of filter visitors that recreate the
filters. They cause the NameSpaceContext to be lost when they recreate the
PropertyNames with a new filterfactory.
They should recreate the property names with namespace context in it.
Perhaps this could be done by creating a subinterface of PropertyName,
NameSpaceAwarePropertyName, and then this could be done::
if (propName instanceof NameSpaceAwarePropertyName) {
return ff.propertyName (propName.getName(),
((NameSpaceAwarePropertyName)propName).getNameSpaceContext());
} else {
return ff.propertyName (propName.getName());
}
Thanks,
Niels

Subject: namespaces part 2
Okay Gabriel took an hour to chat with me through ... I was hoping we could do
more with xpath than the filter 1.1 spec allows us to.
FilterFactory2
- FilterFactoryImplNamespaceAware ideas to be merged into FilterFactory2 (and
thus part of our geotools api)
- FilterFactory2.property( xpath, context )
"Context"
- As for context; the implementation shows the Hint is made up of a single
NamespaceSupport class. Since this is a SAX class it may be hard to use for
people making up a context on the fly as part of a query?
- Gabriel looked at NamespaceContext instead; but is having a hard time finding
a good implementation
Query:
- getQueryHint should cover the use of a NamespaceSupport class as one of the
hints; allowing propertyNames to work
- or make an explicit Query.getNamespaceSupport() method to go with
getPropertyNames()
Neils I will send you our IRC chat.
