Method Detail

getMissingStatements

public static Set<org.apache.jena.rdf.model.Statement> getMissingStatements(org.apache.jena.rdf.model.Model modelA,
                                                                            org.apache.jena.rdf.model.Model modelB)

Collects statements that can be found in model A but not in model B. If A and B are seen as sets of statements, this method returns the difference A\B.

Parameters:

modelA - the model that should be fully contained inside model B.

modelB - the model that should fully contain model A.

Returns:

the difference A\B which is empty if A is a subset of B

modelContainsStatement

public static boolean modelContainsStatement(org.apache.jena.rdf.model.Model model,
                                             org.apache.jena.rdf.model.Statement s)

Checks whether the given statement can be found in the given model. If the given statement contains blank nodes (= Anon nodes) they are replaced by variables.

Parameters:

model - the model that might contain the given statement

s - the statement which could be contained in the given model

Returns:

true if the statement can be found in the model, false otherwise
