| [udig-devel] Multiple FeatureTypes in a Layer |
|
Hi, Is there a way to put multiple FeatureTypes in the same
layer in UDig? We’ve been trying to cut back on the number of
layers we produce in UDig when putting Features on maps, as we have performance
issues that seem to be related to the number of layers we have rather than the
number of features. After digging around in the code and google for some
time I do not believe this is possible, but I wanted to be sure. The way I
understand things, each IGeoResource can only have a single FeatureType and FeatureSource.
LayerImpl, contains a list of IGeoResources, which would lead me to believe
that you can put multiple IGeoResources and therefore multiple FeatureTypes
into a single layer. However, almost all the code in LayerImpl I see
simply uses the first IGeoResource found in the list (getBounds(),
getCrsInternal(), and getSchema() to name a few). Also, the
LayerFactoryImpl does not contain any methods for creating layers with multiple
IGeoResources. Why then does the LayerImpl contain a list of
IGeoResources rather than just a single IGeoResource member variable? Thanks, Joe |
