Graph modelling

Nodes

Domain model class

case class Person(name: String, age: Int)

Neo4j node definition

import com.websudos.neo._

class PersonNode extends Node[Person] {
  
  object name extends StringNode with Index
  
  object name extends IntNode
  
  def fromNode(node: Node[Person]): Person = {
    Person(name, age)  
  }
  
}

When no custom mapping required

class PersonNode extends DefaultNode[Person]

Relationships

class MyRelationship extends Relationship {
  
}

Indexes

Querying

match(node[Person]).where { p =>
  p.name === "Samantha"
}.return(p)

Multi node query

match(node[Person], node[Person]).where { case (p1, p2) =>
  p1.age === p2.age
}.return(p1, p2)
