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.
