Method Detail

execute

public ExtendedIterator execute(TriplePattern query,
                                InfGraph infGraph,
                                Finder data,
                                java.util.HashSet firedRules)

Use the rule to implement the given query. This will instantiate the rule against the query, run the new query against the whole reasoner+rawdata again and then rewrite the results from that query according the rule.

Overrides:

execute in class BRWRule

Parameters:

query - the query being processed

infGraph - link to originating inference graph, may be re-invoked after a pattern rewrite

data - the raw data graph which gets passed back to the reasoner as part of the recursive invocation

firedRules - set of rules which have already been fired and should now be blocked

Returns:

a ExtendedIterator which aggregates the matches and rewrites them according to the rule

completeFor

public boolean completeFor(TriplePattern query)

Return true if this rule is a a complete solution to the given query and the router need look no further

Overrides:

completeFor in class BRWRule
