static GraphQueryResult |
QueryResults.distinctResults(GraphQueryResult queryResult)
Returns a
GraphQueryResult that filters out any duplicate solutions from the supplied queryResult. |
GraphQueryResult |
GraphQuery.evaluate() |
static GraphQueryResult |
QueryResults.limitResults(GraphQueryResult queryResult,
long limit,
long offset)
Returns a
GraphQueryResult that returns at most the specified maximum number of solutions, starting at
the supplied offset. |
static GraphQueryResult |
QueryResults.parseGraphBackground(InputStream in,
String baseURI,
RDFFormat format)
Parses an RDF document and returns it as a GraphQueryResult object, with parsing done on a separate thread in the
background.
IMPORTANT: As this method will spawn a new thread in the background, it is vitally important that the resulting GraphQueryResult be closed consistently when it is no longer required, to prevent resource leaks. |

static boolean |
QueryResults.equals(GraphQueryResult result1,
GraphQueryResult result2)
Compares two graph query results and returns
true if they are equal. |
static GraphQueryResult |
QueryResults.limitResults(GraphQueryResult queryResult,
long limit,
long offset)
Returns a
GraphQueryResult that returns at most the specified maximum number of solutions, starting at
the supplied offset. |
