Chapter 441: OperatorNode

Core Idea

This node represents basic mathematical and logical operations like addition, subtraction or comparisons (e.g. equal()).

Key Concepts

• aNode : Node: The first input.
• bNode : Node: The second input.
• isOperatorNode : boolean (readonly): This flag can be used for type testing.
• op : string: The operator.

Reference Tables

Constructor

Signature
new OperatorNode( op : string, aNode : Node, bNode : Node, …params : Node )

Properties

Property	Description
.aNode : Node	The first input.
.bNode : Node	The second input.
.isOperatorNode : boolean (readonly)	This flag can be used for type testing.
.op : string	The operator.

Methods

Method	Description
.generateNodeType( builder : NodeBuilder, output : string ) : string	This method is overwritten since the node type is inferred from the operator and the input node types.
.getOperatorMethod( builder : NodeBuilder, output : string ) : string	Returns the operator method name.

Key Takeaways

1. OperatorNode extends: EventDispatcher → Node → TempNode
2. Most relevant properties: aNode, bNode, isOperatorNode, op.
3. Key methods: generateNodeType, getOperatorMethod.
