Class QuerySpecBuilder

java.lang.Object

org.eclipse.rdf4j.sail.lucene.QuerySpecBuilder

All Implemented Interfaces:

SearchQueryInterpreter

public class QuerySpecBuilder
extends Object
implements SearchQueryInterpreter

A QueryInterpreter creates a set of QuerySpecs based on Lucene-related StatementPatterns that it finds in a TupleExpr.

QuerySpecs will only be created when the set of StatementPatterns is complete (i.e. contains at least a matches and a query statement connected properly) and correct (query pattern has a literal object, matches a resource subject, etc.).

void	process(org.eclipse.rdf4j.query.algebra.TupleExpr tupleExpr, org.eclipse.rdf4j.query.BindingSet bindings, Collection<SearchQueryEvaluator> result) Appends a set of QuerySpecs embodying all necessary information to perform the Lucene query embedded in a TupleExpr.

Method Detail

process

@Deprecated
public Set<QuerySpec> process(org.eclipse.rdf4j.query.algebra.TupleExpr tupleExpr,
                                          org.eclipse.rdf4j.query.BindingSet bindings)
                                   throws org.eclipse.rdf4j.sail.SailException

Deprecated.

Returns a set of QuerySpecs embodying all necessary information to perform the Lucene query embedded in a TupleExpr. To be removed, prefer process(TupleExpr tupleExpr, BindingSet bindings, Collection <SearchQueryEvaluator> result).

Throws:

org.eclipse.rdf4j.sail.SailException

process

public void process(org.eclipse.rdf4j.query.algebra.TupleExpr tupleExpr,
                    org.eclipse.rdf4j.query.BindingSet bindings,
                    Collection<SearchQueryEvaluator> result)
             throws org.eclipse.rdf4j.sail.SailException

Appends a set of QuerySpecs embodying all necessary information to perform the Lucene query embedded in a TupleExpr.

Specified by:

process in interface SearchQueryInterpreter

Parameters:

tupleExpr - the TupleExpr to process.

bindings - any bindings.

result - the Collection to add any SearchQueryEvaluators to.

Throws:

org.eclipse.rdf4j.sail.SailException
