public class ViewInstance<T extends IViewDef> extends Object
View instances relate variables (usually those of of a SPARQL query subject to rewriting) to the variables and constants of a view. A view instance is comprised of - A view definition - A binding, which relates query variables to variables of the view and constants TODO View instances should implement a common interface with mappings
