Chapter 477: SplitNode

Core Idea

This module is part of the TSL core and usually not used in app level code. SplitNode represents a property access operation which means it is used to implement any .xyzw, .rgba and stpq usage on node objects. For example:

Key Concepts

• components : string: The components that should be accessed.
• isSplitNode : boolean (readonly): This flag can be used for type testing.
• node : Node: The node that should be accessed.

Code Examples

const redValue = color.r;

• What it demonstrates: Typical usage of SplitNode.

Reference Tables

Constructor

Signature
new SplitNode( node : Node, components : string )

Properties

Property	Description
.components : string	The components that should be accessed.
.isSplitNode : boolean (readonly)	This flag can be used for type testing.
.node : Node	The node that should be accessed.

Methods

Method	Description
.generateNodeType( builder : NodeBuilder ) : string	This method is overwritten since the node type is inferred from requested components.
.getComponentType( builder : NodeBuilder ) : string	Returns the component type of the node's type.
.getScope() : Node	Returns the scope of the node.
.getVectorLength() : number	Returns the vector length which is computed based on the requested components.

Key Takeaways

1. SplitNode extends: EventDispatcher → Node
2. Most relevant properties: components, isSplitNode, node.
3. Key methods: generateNodeType, getComponentType, getScope, getVectorLength.
