Chapter 752: NodeFunction

Core Idea

Base class for node functions. A derived module must be implemented for each supported native shader language. Similar to other Node* modules, this class is only relevant during the building process and not used in user-level code.

Key Concepts

• inputs : Array.<NodeFunctionInput>: The function's inputs.
• name : string: The name of the uniform.
• precision : string: The precision qualifier.
• type : string: The node type. This type is the return type of the node function.

Reference Tables

Constructor

Signature
new NodeFunction( type : string, inputs : Array.<NodeFunctionInput>, name : string, precision : string )

Properties

Property	Description
.inputs : Array.<NodeFunctionInput>	The function's inputs.
.name : string	The name of the uniform.
.precision : string	The precision qualifier.
.type : string	The node type. This type is the return type of the node function.

Methods

Method	Description
.getCode( name : string ) : string (abstract)	This method returns the native code of the node function.

Key Takeaways

1. Most relevant properties: inputs, name, precision, type.
2. Key methods: getCode.
