Class ASTDeferredIVResolution

java.lang.Object

com.bigdata.rdf.sparql.ast.eval.ASTDeferredIVResolution

public class ASTDeferredIVResolution
extends Object

This class provides batch resolution of internal values, which were left unresolved during query/update preparation. Values, which are processed: any BOp arguments, ValueExpressions, and specific values stored in annotations (for example, SERVICE_REF in ServiceNode).

Class performs efficient batch resolution of RDF Values against the database during query preparation. This efficiency is important on a cluster and when a SPARQL query or update contains a large number of RDF Values.
