| DIGIteratedQueryTranslator | | public DIGIteratedQueryTranslator(String subject, String predicate, String object)(Code) | | Construct a query translator for the given query parameters.
Parameters:
subject - Represents the incoming subject to trigger against
Parameters:
predicate - Represents the incoming predicate to trigger against
Parameters:
object - Represents the incoming object to trigger against |
| expandQuery | | abstract protected Iterator expandQuery(TriplePattern pattern, DIGAdapter da)(Code) | | Takes the incoming query pattern and expands it out to a series of subsidary
triple patterns that will be taken as queries in their own right.
Parameters:
pattern - The incomimg query pattern
Parameters:
da - The DIG adapter currently being used to communicate with the DIG reasoner An iterator over a series of TriplePattern's that representthe expanded query |
| find | | public ExtendedIterator find(TriplePattern pattern, DIGAdapter da)(Code) | | Expand the given pattern to a series of more grounded patterns, and collate
the results of querying with each of these expanded patterns. This is used in
cases where the incoming query is too ungrounded to pass to DIG in one go, e.g.
* rdfs:subClassOf *. The strategy is to expand one of
the ungrounded terms to form a series of queries, then solve each of these
queries separately.
Parameters:
pattern - The pattern to translate to a DIG query
Parameters:
da - The DIG adapter through which we communicate with a DIG reasoner |
