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.
