Member Function Documentation

Triple NTriplesFilePool::fetch ( Triple simplePattern,

LoopState & loopState,

unsigned long max_results = 0

) const [virtual]

Get the first triple which matches the pattern, and then (on following calls) get the next matching triples.
max_results is a hint which can improve performance if you know ahead of time that you will not be iterating more than some number of times.
Reimplemented from TripleSource.

void NTriplesFilePool::replace ( Symbol old,

Symbol replacement

) [virtual]
