NAME¶
Search::Xapian::PositionIterator - Iterate over sets of positions.
DESCRIPTION¶
This iterator represents a stream of positions for a term. It overloads
"++" for advancing the iterator, or you can explicitly call the
"inc" method. This class also overloads "eq",
"ne", "==", "!=", "" (stringification)
and "0+" (conversion to an integer).
METHODS¶
- new
- Constructor. Defaults to an uninitialized iterator.
- clone
- inc
- Advance the iterator by one. (Called implictly by
"++" overloading).
- skip_to <termpos>
- Skip the iterator to term position termpos, or the first
term position after termpos if termpos isn't in the list of term positions
being iterated.
- equal <term>
- Checks if a term is the same as this term. Also overloaded
to the "eq" and "==" operators.
- nequal <term>
- Checks if a term is different from this term. Also
overloaded to the "ne" and "!=" operators.
- get_termpos
- Return the term position the iterator is currently on. Also
implemented as conversion to an integer.
- get_description
- Return a description of this object. Also implemented as
stringification.
