interface of a generic filter iterator.
provides sequential access to the constraints of a filter.
virtual bool siena::filter::iterator::next | ( | ) | [pure virtual] |
moves this iterator to the next attribute in the sequence.
true
if the constraint pointed to by this iterator before this call to next() is not the last one in its filter. In this case, after this call to next(), this iterator will point to the next constraint. false
if this iterator points to the last constraint or to the end of the sequence. In this case, after this call to next(), this iterator will point to an invalid constraint representing the end of the sequence.
