public class ResultNode

extends VirtualNode

A ResultNode is a virtual node, used to represent the result of executing an arbitrary search query.

The fields of this node correspond to the fields of the result of the query. Consequently, and unlike real a real node, a ResultNode does not necessarilly have number, owner or otype fields.

Additionally, the fields of this node can have arbitrary names, specified by the field aliases in the search query.

The parent builder of a ResultNode is always a ResultBuilder, that contains info on the node's fields.
