Chapter 394: CodeNode

Core Idea

This class represents native code sections. It is the base class for modules like FunctionNode which allows to implement functions with native shader languages.

Key Concepts

• code : string: The native code.
• global : boolean: This flag is used for global cache.
• includes : Array.<Node>: An array of includes
• isCodeNode : boolean (readonly): This flag can be used for type testing.
• language : 'js' | 'wgsl' | 'glsl': The used language.

Reference Tables

Constructor

Signature
`new CodeNode( code : string, includes : Array.<Node>, language : 'js'

Properties

Property	Description
.code : string	The native code.
.global : boolean	This flag is used for global cache.
.includes : Array.<Node>	An array of includes
.isCodeNode : boolean (readonly)	This flag can be used for type testing.
`.language : 'js'	'wgsl'

Methods

Method	Description
.getIncludes( builder : NodeBuilder ) : Array.<Node>	Returns the includes of this code node.
.setIncludes( includes : Array.<Node> ) : CodeNode	Sets the includes of this code node.

Key Takeaways

1. CodeNode extends: EventDispatcher → Node
2. Most relevant properties: code, global, includes, isCodeNode.
3. Key methods: getIncludes, setIncludes.
