Search::Query::Clause - part of a Dialect
my $clause = Search::Query::Clause->new( field => 'color', op => '=', value => 'green', ); my $query = Search::Query->parser->parse("color=red"); $query->add_or_clause( $clause ); print $query; # +color=red color=green
A Clause object represents a leaf in a Query Dialect tree.
This class is a subclass of Rose::ObjectX::CAF. Only new or overridden methods are documented here.
Returns true if the Clause has child Clauses.
Returns the number of child Clauses if is_tree() is true.
Returns undef if is_tree() is false.
Returns Clause as a string. Like Dialect, string-like operators are overloaded to call stringify().
NOTE that stringify() is not necessarily called by the parent Dialect object when the Dialect object is stringifying itself.
