OdDbGraphNode Class

Class Hierarchy

Syntax

C++

class OdDbGraphNode : public OdRxObject;

File

DbGraph.h

Description

This class implements generic node objects for generic graphs.

Remarks

A graph consists of a collection of nodes bi-directionally linked by directional edges.

An edge connected to a node is represented as a pointer or reference to the node at the other end of the edge.

References are classified as either incoming or outgoing. Every incoming reference has a corresponding outgoing reference and vice versa.

Each GraphNode object can have any number of references associated with it, enabling the implementation of any graph structure.
