makVrv::DtOsgEarthFeatureDataBroker Class Reference

DtOsgEarthFeatureDataBroker listens to osgEarth feature layers (i.e. model layers with a feature source) and dispatches post-processor routines whenever new data pages in.

The class will accept "postMerge" callbacks. When a new subgraph pages in and merges into the scene graph, the decorator will invoke the callbacks on the data.
