List of exportStatements() Examples

Examples of exportStatements()

org.openrdf.repository.RepositoryConnection.exportStatements()
Exports all statements with a specific subject, predicate and/or object from the repository, optionally from the specified contexts. @param subj The subject, or null if the subject doesn't matter. @param pred The predicate, or null if the predicate doesn't matter. @param obj The object, or null if the object doesn't matter. @param contexts The context(s) to get the data from. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository. @param handler The handler that will handle the RDF data. @param includeInferred if false, no inferred statements are returned; if true, inferred statements are returned if available @throws RDFHandlerException If the handler encounters an unrecoverable error. @deprecated Use{@link #exportMatch(Resource,URI,Value,boolean,RDFHandler,Resource)}instead
