Remarks

This function allows fine-grained object access to a FeatureLayer, a RasterLayer or a StandaloneTable by returning IFeatureClass, IRaster or ITable respectively. If the layer or standalone table has any joins, the returned object will not contain the joined portion. In addition any field visibility or field alias set to the layer in the source map document will be ignored as it returns the underlying data source.
