Class ResultSetCompare

java.lang.Object

org.apache.jena.sparql.resultset.ResultSetCompare

public class ResultSetCompare
extends java.lang.Object

Comparison of ResultSets. Note that reading ResultSets is destructive so consider using ResultSetRewindable from ResultSetFactory.makeRewindable(org.apache.jena.rdf.model.Model)

Method Detail

equalsByValue

public static boolean equalsByValue(ResultSet rs1,
                                    ResultSet rs2)

Compare two result sets for equivalence. Equivalence means: A row rs1 has one matching row in rs2, and vice versa. A row is only matched once. Rows match if they have the same variables with the same values. bNodes must map to a consistent other bNodes. Value comparisons of nodes. Destructive - rs1 and rs2 are both read, possibly to exhaustion.

Parameters:

rs1 -

rs2 -

Returns:

true if they are equivalent

equalsByTest

public static boolean equalsByTest(java.util.Collection<Binding> b1,
                                   java.util.Collection<Binding> b2,
                                   EqualityTest match)

equalsByTerm

public static boolean equalsByTerm(ResultSet rs1,
                                   ResultSet rs2)

compare two result sets for equivalence. Equivalence means: A row rs1 has one matching row in rs2, and vice versa. A row is only matched once. Rows match if they have the same variables with the same values, bNodes must map to a consistent other bNodes. Term comparisons of nodes. Destructive - rs1 and rs2 are both read, possibly to exhaustion.

Parameters:

rs1 -

rs2 -

Returns:

true if they are equivalent

equalsByValueAndOrder

public static boolean equalsByValueAndOrder(ResultSet rs1,
                                            ResultSet rs2)

Compare two result sets for equivalence. Equivalence means: Each row in rs1 matches the same index row in rs2. Rows match if they have the same variables with the same values, bNodes must map to a consistent other bNodes. Value comparisons of nodes. Destructive - rs1 and rs2 are both read, possibly to exhaustion.

Parameters:

rs1 -

rs2 -

Returns:

true if they are equivalent

equalsByTermAndOrder

public static boolean equalsByTermAndOrder(ResultSet rs1,
                                           ResultSet rs2)

compare two result sets for equivalence. Equivalence means: Each row in rs1 matches the same index row in rs2. Rows match if they have the same variables with the same values, bNodes must map to a consistent other bNodes. RDF term comparisons of nodes. Destructive - rs1 and rs2 are both read, possibly to exhaustion.

Parameters:

rs1 -

rs2 -

Returns:

true if they are equivalent

equalsExact

public static boolean equalsExact(ResultSet rs1,
                                  ResultSet rs2)

compare two result sets for exact equality equivalence. Exact equalitymeans: Each row in rs1 matches the same index row in rs2. Rows match if they have the same variables with the same values, bNodes must have same labels Destructive - rs1 and rs2 are both read, possibly to exhaustion.

Parameters:

rs1 -

rs2 -

Returns:

true if they are equivalent

isomorphic

public static boolean isomorphic(ResultSet rs1,
                                 ResultSet rs2)

Compare two result sets for bNode isomorphism equivalence. Only does RDF term comparison.

equal

public static boolean equal(Binding bind1,
                            Binding bind2,
                            EqualityTest test)

Compare two bindings, use the node equality test provided
