NAME
REST::Neo4p::Path - Container for Neo4j path elements
SYNOPSIS
use REST::Neo4p::Query;
$query = REST::Neo4p::Query->new(
'START n=node(0), m=node(1) MATCH p=(n)-[*..3]->(m) RETURN p'
);
$query->execute;
$path = $query->fetch->[0];
@nodes = $path->nodes;
@relns = $path->relationships;
while ($n = shift @nodes) {
my $r = shift @relns;
print $r ? $n->id."-".$r->id."->" : $n->id."\n";
}
DESCRIPTION
REST::Neo4p::Path provides a simple container for Neo4j paths as returned by Cypher queries. Nodes and relationships are stored in path order.
Currently, creating de novo instances of this class is really the job of REST::Neo4p::Query.
METHODS
- nodes()
-
@nodes = $path->nodes;
Get the nodes in path order.
- relationships()
-
@relationships = $path->relationships;
Get the relationships in path order.
- as_simple()
-
$a = $path->as_simple; @simple_nodes = grep { $_->{_node} } @$a; @simple_relns = grep { $_->{_relationship} } @$a;
Get the path as an array of simple node and relationship hashes (see "as_simple()" in REST::Neo4p::Node, "as_simple()" in REST::Neo4p::Relationship).
