Hi, I have a question on developing an datastore. For a research project I have to develope a datastore for hibernate spatial. I've started with the tutorial of extending the ContentDataStore in your 8.0-M0 User Guide and working with POJOs predefined in sourcecode. For our project this is enough. Dynamically creation of Hibernate Spatial POJOs will be a nice feature and I will maybe integrate this when I have time for that (and the knowhow). :-)
The datatore is developed in a first result for reading all data from a table via hibernate spatial. This till work. Now I want to implement the filter mechanism for my datastore. For that I have to convert the filter (geotools/opengis) to a hibernate criterion of hibernate spatial. When I have a look on JDBCDataStore I found the class FilterToSQL which implements all the visitor-methods for the possible filter operators. Will be using a visitor, implementing all this methods, the best practise for me too, and where should I integrate the conversion into the whole datastore implementation (FeatureSource, FeatureReader)? I hope anyone can say me, as a newbie with geotools, if I'm on the right way and give me some tips and tricks for including the filter conversion. Thanks in advance.
