Hi list,
I have been off for a seminar for last week, and did not make much progress
on our side.
Though, I would like to put a few words on what I am working on by the
moment.
Current tasks :
1. demo using JMapPane. Two JMapPanes, with one using a cached datastore of
the datastore used by the other, so we can see the difference at rendering
time.
Experimenting this, I found my DataCache was not truly DataStore compliant !
So first task will be to have DataCache pass AbstractDataStoreTest. Don't
know how to handle the fact I intended to make my DataCache read-olny of a
first attempt. But write-through should be not too hard to implement.
2. find how to split a query to get the spatial restriction in it, as the
cache tracks queries by their bounds. I have to look more closely to
FilterVisitors.
3. design a realistic eviction strategy for the cache. My idea is to pick an
appropriate node in the query bounds tree and remove corresponding features
from the cache. The org.geotools.index.RTree offers no simple way to do
this.
Any suggestions welcome :)
Christophe
