Class ProjectedOp

java.lang.Object
org.aksw.jena_sparql_api.algebra.utils.ProjectedOp
public class ProjectedOp extends Object
TODO Maybe rename to OpWithModifiers The intent of this class is to capture a 'core' op together with specific modifiers to be applied afterwards: - projection, distinct and filters Issue: In which order to apply these? distinct and filters can be swapped; I suppose a reasonable order could be: filter, project, distinct Further, I think a OpWithModifiers is itself an Op again, so that the distinct / project / filter can be nested.
