Interface IFeatureNoDataValuedItem

All Superinterfaces:
ICollectionValue, IItem
All Known Subinterfaces:
IFeatureNoDataAtomicValuedItem, IModuleNodeItem
public interface IFeatureNoDataValuedItem extends IItem
This feature interface represents an item that has no associated value data.

This will occur when an IItem represents a Metaschema definition or instance that is not associated with data. This is typical when constructing items for querying a Metaschema directly, instead of content which will always have data.
