NAME

Neo4j::Types - Common Neo4j type system

VERSION

version 2.00

DESCRIPTION

Packages in this distribution represent Cypher types for use with the Neo4j graph database system. As a user of a Neo4j driver distribution supporting these types, you can find details on the available methods for each type and their behaviour in the documentation of the individual modules.

• Neo4j::Types::Node

• Neo4j::Types::Relationship

• Neo4j::Types::Path

• Neo4j::Types::ByteArray

• Neo4j::Types::DateTime

• Neo4j::Types::Duration

• Neo4j::Types::Point

The module Neo4j::Types itself contains no code, but you can use it as a shortcut to load all the modules listed above.

Additionally, generic implementations are offered for those types which Neo4j allows to be used as a query parameter. See Neo4j::Types::Generic for details.

Given a Perl scalar, you can determine whether it represents a specific type of Neo4j value by using the isa operator.

 use v5.36;
 $is_node = $value isa Neo4j::Types::Node;
 
 # Older versions of Perl:
 use Scalar::Util 'blessed';
 $is_node = blessed $value && $value->isa( 'Neo4j::Types::Node' );

Version 2 of Neo4j::Types is targeting Perl v5.16 and newer. Patches will be accepted to address issues with Perl versions as old as v5.10.1 as long as practical.

IMPLEMENTOR GUIDANCE

The Neo4j Cypher Manual describes a variety of types. For a discussion of typical ways to implement these in Perl, see Neo4j::Types::ImplementorNotes.
