Class QueryNodeWithBindingSet

java.lang.Object

com.bigdata.rdf.sparql.ast.QueryNodeWithBindingSet

public class QueryNodeWithBindingSet
extends Object

Class for wrapping a query node and an associated binding set (as starting point for evaluating the query). Mainly used in the context of the AST optimizer pipeline. Typically, these optimizers do only modify the AST, but in some cases they may involve manipulation of the binding sets (see for instance the ASTStaticBindingsOptimizer).
