KinoSearch::Search::PolyQuery - Base class for composite Query objects.
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
sub walk { my $query = shift; if ( $query->isa("KinoSearch::Search::PolyQuery") ) { if ( $query->isa("KinoSearch::Search::ORQuery") ) { ... } elsif ( $query->isa("KinoSearch::Search::ANDQuery") ) { ... } elsif ( $query->isa("KinoSearch::Search::RequiredOptionalQuery") ) { ... } elsif ( $query->isa("KinoSearch::Search::NOTQuery") ) { ... } } else { ... } }
PolyQuery serves as a shared base class for ANDQuery, ORQuery, NOTQuery, and RequiredOptionalQuery. All of these classes may serve as nodes in composite Query with a tree structure which may be walked.
KinoSearch::Search::PolyQuery isa KinoSearch::Search::Query isa KinoSearch::Object::Obj.
