I'm using a CIMUniqueValueRenderer on a feature layer, and when iterating over the features for the layer, I need to retrieve the symbol that applies to a given feature. Is there a way to retrieve the applicable symbol without having to iterate over the renderer's fields, groups, and values and looking for a match? Basically, I'm looking for the equivalent of the ILookupSymbol interface that exists in ArcObjects where you pass in the feature and get back the symbol. Thanks.
