So I kind of see where you are going with this. It gets a bit strange around
the ReferencedEnvelope / ReferencedEnvelope3D level.
-1
The FeatureCollections.getBounds() contract cannot be respected for your
ReferenceEnvelope or ReferenceEnvelope3D. I know you only want to use this as
part of a query, but I don't want our envelope story to get even more strange
if we can avoid it.
I don't want to impose a ReferenceEnvelope interface as that defeats the
purpose of making ReferenceEnvelope an easy to use middle ground between JTS
Envelope and the BoundingBox interface. If we had to go this way we would end
up going with BoundingBox / Envelope interface and modifying them to be more
method compatible with JTS Envelope.
Can you consider switching around your class hierarchy?
1) BBoxEnvelope extension of JTS Envelope
- Write this so it can work as a 2D or 3D envelope (depending on how the
constructor is called)
- the existing BoundingBox / Envelope interfaces should be sufficient?
2) Make ReferencedEnvelope extend BBoxEnvelope; and allow it to cover the 2D or
3D use-case
Finally there is no need to make FilterFactory more crazy, treat your
ReferencedEnvelope as a prameter object:
BBOX3D bbox( Expression geometry, ReferencedEnvelope bbox, MatchAction
matchAction);
Waiting your reply, I am afraid we cannot make a ReferencedEnvelope interface
(as an implementation class lots of downstream code makes direct reference to
this one).
