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.
