Returns the number of triples that are returned by the TriplesResponse.getTriples().

Specified by:

getSize in interface TriplesResponse

getPayload

public Iterable<Triple> getPayload()

Description copied from interface: TPFResponse

While TriplesResponse.getTriples() returns an iterator over all triples contained in the given TPF response, this method here returns an iterator only over the matching triples that have been requested.

Specified by:

getPayload in interface TPFResponse

getPayloadSize

public int getPayloadSize()
