NAME

ODO::Graph::Query::VariablePatternMap

SYNOPSIS

DESCRIPTION

METHODS

add( $stmt, $item )

add_list( $stmt, $list )

get_result_graph( [ $graph ])

 Gathers all of the triples for the patterns in the query
 and results the concrete results in the form of an L<ODO::Graph>.
 
 If an L<ODO::Graph> is specified as a parameter, the method will
 fill it with the results instead of creating a new graph object.

get_results_for_pattern( $stmt )

 Returns the array reference that potentially contains results
 that can fill this triple pattern.
 

make_query_list( $stmt_match )

count_pattern_results( $stmt )

clear_pattern_results( $stmt )

invalidate_results( $stmt, $resultsGraph )

known_variable_count( $stmt )

Internal methods

__is_pattern_key( $pk )

__make_pattern_key( $stmt )

 Makes a key such that variable names are included while all other
 nodes are replaced by a star.

__key_to_triple_match( $key )

 Create a TripleMatch based on the key with the non-variable
 components as Any nodes.

__compare_pattern( $pattern, $stmt )

__prune_patterns( $stmt, $inter_results )
