Domain entities
Domain entities can be wrapped around a node. The same approach can be used with relationships.
The source code of the examples isfound at: Person.java |
First off, store the node and make it accessible inside the package:
private final Node underlyingNode;
Person( GraphDatabaseService databaseService, Transaction transaction, Node personNode )
{
this.databaseService = databaseService;
this.transaction = transaction;
this.underlyingNode = personNode;
}
protected Node getUnderlyingNode()
{
return underlyingNode;
}
Delegate attributes to the node:
public String getName()
{
return (String)underlyingNode.getProperty( NAME );
}
Make sure to override these methods:
@Override
public int hashCode()
{
return underlyingNode.hashCode();
}
@Override
public boolean equals( Object o )
{
return o instanceof Person &&
underlyingNode.equals( ( (Person)o ).getUnderlyingNode() );
}
@Override
public String toString()
{
return "Person[" + getName() + "]";
}
