Neo4j::Bolt::Relationship - Representation of a Neo4j Relationship
$q = 'MATCH ()-[r]-() RETURN r'; $reln = ( $cxn->run_query($q)->fetch_next )[0]; $reln_id = $reln->{id}; $reln_type = $reln->{type}; $start_node_id = $reln->{start}; $end_node_id = $reln->{end}; $properties = $reln->{properties} // {}; %properties = %$properties; $value1 = $reln->{properties}->{property1}; $value2 = $reln->{properties}->{property2}; $hashref = $reln->as_simple;
Neo4j::Bolt::Relationship instances are created by executing a Cypher query that returns relationships from a Neo4j database. Their properties and metadata can be accessed as shown in the synopsis above.
This package inherits from Neo4j::Types::Relationship, which offers an object-oriented interface to the relationship's properties and metadata. This is entirely optional to use.
If a query returns the same relationship twice, two separate Neo4j::Bolt::Relationship instances will be created.
This package inherits all methods from Neo4j::Types::Relationship. The following additional method is provided:
$simple = $reln->as_simple; $reln_id = $simple->{_relationship}; $reln_type = $simple->{_type}; $start_node_id = $simple->{_start}; $end_node_id = $simple->{_end}; $value1 = $simple->{property1}; $value2 = $simple->{property2};
Get relationship as a simple hashref in the style of REST::Neo4p.
The value of properties named _relationship, _type, _start or _end will be replaced with the relationship's metadata.
