Hi.
I assume you are referring to like using PostGIS?
The DataStore does return a list of type names for each table registered in
geometry_columns; you can review the FeatureType for each type name mentioned
(which contains the information about which "geometry columns" are marked; they
are represented as an instance of GoemetryDescriptor).
I don't think there is a select; a good old fashion for loop should do the
trick ... something like:
for( Name typeName : dataStore.getNames() ){
SimpleFeatureType schema = dataStore.getSchema( typeName );
...
}
More information here:
