Examples of org.openrdf.repository.RepositoryConnection.export()

org.openrdf.repository.RepositoryConnection.export()
Exports all explicit statements in the specified contexts to the supplied RDFHandler. @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. @throws RDFHandlerException If the handler encounters an unrecoverable error.
