NAME

Neo4j::Bolt::Node - Representation of a Neo4j Node

SYNOPSIS

 $q = 'MATCH (n) RETURN n';
 $node = ( $cxn->run_query($q)->fetch_next )[0];
 
 $node_id    = $node->{id};
 $labels     = $node->{labels} // [];
 @labels     = @$labels;
 $properties = $node->{properties} // {};
 %properties = %$properties;
 
 $value1 = $node->{properties}->{property1};
 $value2 = $node->{properties}->{property2};
 
 $hashref = $node->as_simple;

DESCRIPTION

Neo4j::Bolt::Node instances are created by executing a Cypher query that returns nodes from a Neo4j database. Their properties and metadata can be accessed as shown in the synopsis above.

If a query returns the same node twice, two separate Neo4j::Bolt::Node instances will be created.

METHODS

as_simple()

 $simple  = $node->as_simple;
 
 $node_id = $simple->{_node};
 @labels  = @{ $simple->{_labels} };
 $value1  = $simple->{property1};
 $value2  = $simple->{property2};

Get node as a simple hashref in the style of REST::Neo4p.

The value of properties named _node or _labels will be replaced with the node's metadata.
