Chapter 376: ArrayElementNode

Core Idea

Base class for representing element access on an array-like node data structures.

Key Concepts

• indexNode : Node: The index node that defines the element access.
• isArrayElementNode : boolean (readonly): This flag can be used for type testing.
• node : Node: The array-like node.

Reference Tables

Constructor

Signature
new ArrayElementNode( node : Node, indexNode : Node )

Properties

Property	Description
.indexNode : Node	The index node that defines the element access.
.isArrayElementNode : boolean (readonly)	This flag can be used for type testing.
.node : Node	The array-like node.

Methods

Method	Description
.generateNodeType( builder : NodeBuilder ) : string	This method is overwritten since the node type is inferred from the array-like node.
.getMemberType( builder : NodeBuilder, name : string ) : string	This method is overwritten since the member type is inferred from the array-like node.

Key Takeaways

1. ArrayElementNode extends: EventDispatcher → Node
2. Most relevant properties: indexNode, isArrayElementNode, node.
3. Key methods: generateNodeType, getMemberType.
