ITupleCursorthrough the distinct term identifiers for some
AccessPath. Each time a new
ITupleis visited, the term identifier for the first position in that tuple is decoded and its successor is formed. The source
ITupleCursoris then advanced to the key having that term identifier in its first position and
IRawTripleStore#NULLin its 2nd and 3rd position. For example, if the
ITuplewhose term identifiers are, in the order in which they appear in the key:
[ 12, 4, 44 ]Then the source
ITupleCursorwill be advanced to the key:
[ 13, 0, 0 ]This is used to efficiently visit the distinct terms actually appearing in the subject, predicate, or object position of
SPOs in the database.
