fiftyone.mobile.detection.entities.Node

fiftyone.mobile.detection.entities.stream.Node

All Implemented Interfaces:

Comparable<Node>

Direct Known Subclasses:

NodeV31, NodeV32

public abstract class Node
extends Node

Represents a Entities.Node which can be used with the Stream data set. NumericChidren and RankedSignatureIndexes are not loaded into memory when the entity is constructed, they're only loaded from the data source when requested.

Objects of this class should not be created directly as they are part of the internal logic.
