MapSubLayerSettings Class

Normalized representation of a MapSubLayerProps for which values have been validated and default values have been applied where explicit values not defined. A map sub layer represents a set of objects within the layer that can be controlled separately. These are produced only from map servers that produce images on demand and are not supported by tiled (cached) servers. This class can represent a hierarchy, in this case a sub layer is visible only if all its ancestors are also visible.
