Method: Neo4j::Wrapper::NodeMixin::ClassMethods#new

Defined in:

lib/neo4j-wrapper/node_mixin/class_methods.rb

#new(*args) ⇒ Object Also known as: create

Creates a new node or loads an already existing Neo4j node.

You can use two callback method to initialize the node init_on_load - this method is called when the node is loaded from the database init_on_create - called when the node is created, will be provided with the same argument as the new method

Does

• sets the neo4j property ‘_classname’ to self.class.to_s

• creates a neo4j node java object (in @_java_node)

If you want to provide your own initialize method you should instead implement the method init_on_create method.

Examples:

Create your own Ruby wrapper around a Neo4j::Node java object

class MyNode
  include Neo4j::NodeMixin
end

node = MyNode.new(:name => 'jimmy', :age => 23)

Using your own initialize method

class MyNode
  include Neo4j::NodeMixin

  def init_on_create(name, age)
     self[:name] = name
     self[:age] = age
  end
end

node = MyNode.new('jimmy', 23)

Parameters:

• args —

  typically a hash of properties, but could be anything which will be handled in the super method

Returns:

• the object return from the super method
