Classes in com.bigdata.rdf.internal.constraints used by com.bigdata.bop.rdf.aggregate

Class and Description
INeedsMaterialization Some IVValueExpression need materialized terms to perform their evaluation.
INeedsMaterialization.Requirement
IPassesMaterialization Some IVValueExpression evaluate to one of their arguments, and if a INeedsMaterialization is in the expressions parent path, the parent needs to materialize the expression's arguments.
