NAME
Neo4j::Driver::Record - Container for Cypher result values
VERSION
version 1.02
SYNOPSIS
$record = $session->execute_write( sub ($transaction) {
return $transaction->run( ... )->fetch;
});
$value = $record->get('name'); # field key
$value = $record->get(0); # field index
# Shortcut for records with just a single key
$value = $record->get;DESCRIPTION
Container for Cypher result values. Records are returned from Cypher query execution, contained within a Result. A record is a form of ordered map and, as such, contained values can be accessed by either positional index or textual key.
To obtain a record, call "fetch" in Neo4j::Driver::Result.
METHODS
Neo4j::Driver::Record implements the following methods.
get
$value1 = $record->get('field_key');
$value2 = $record->get(2);Get a value from this record, either by field key or by zero-based index.
When called without parameters, get() will return the first field. If there is more than a single field, a warning in the category ambiguous will be issued.
$value = $session->run('RETURN "It works!"')->single->get;
$value = $session->run('RETURN "warning", "ambiguous"')->single->get;Values are returned from Neo4j as Neo4j::Types objects and as simple Perl references / scalars. For details and for known issues with type mapping see Neo4j::Driver::Types.
data
$hashref = $record->data;
$value = $hashref->{field_key};Return the keys and values of this record as a hash reference.
