Mapping Methods

The get() or alias() method of the UltipaResponse class returns a DataItem, which embeds the query result. You should use the as<Type>() method of DataItem to cast the result to the appropriate driver type.

response = Conn.uql("find().nodes() as n return n{*} limit 5")
nodeList = response.alias("n").asNodes()

The result n coming from the database contains five nodes, each of the NODE type. The asNodes() method converts them as a list of Node objects.

Type mapping methods available on DataItem:

Driver Types

Objects of all driver types support getter methods to retrieve the value of a field and setter methods to set the value of a field, even if they are not explicitly listed below.

Node

A Node object has the following fields:
