class Graph

Graph is the base class for node graphs

A Graph is a hierarchy of GraphNode objects connected using GraphPlug objects.

Hierarchy

class Graph < class SelectableNode < class DeletableNode < class Node

Children classes : class RenderGraph

Members

Methods:

result GraphNode createmixnode ( ) This method is called when the user wants to combine two outputs or an output and a connection.

Inherited from class SelectableNode

Plugs:

boolean Selected R True if the node is selected. Don't use this plug directly to select a node, use the Document's modifier select method.

Inherited from class Node

Plugs:

string Name RW The node name
