Class BufferedSplitter

java.lang.Object

org.eclipse.rdf4j.sail.shacl.ast.planNodes.BufferedSplitter

All Implemented Interfaces:

PlanNodeProvider

public class BufferedSplitter
extends Object
implements PlanNodeProvider

Author:

Håvard Ottestad

Allows the iterator of one planNode to be used by multiple other nodes by buffering all results from the parent iterator. This will potentially take a fair bit of memory, but maybe be useful for perfomance so that we don't query the underlying datastores for the same data multiple times.
