Chapter 460: ReferenceElementNode

Core Idea

This class is only relevant if the referenced property is array-like. In this case, ReferenceElementNode allows to refer to a specific element inside the data structure via an index.

Key Concepts

• isReferenceElementNode : boolean (readonly): This flag can be used for type testing.
• isReferenceElementNode : boolean (readonly): This flag can be used for type testing.
• referenceNode : ReferenceBaseNode: Similar to ReferenceBaseNode#reference, an additional property references to the current node.
• referenceNode : ReferenceNode: Similar to ReferenceNode#reference, an additional property references to the current node.

Constructor

Signature
new ReferenceElementNode( referenceNode : ReferenceNode, indexNode : Node )

Properties

Property	Description
.isReferenceElementNode : boolean (readonly)	This flag can be used for type testing.
.isReferenceElementNode : boolean (readonly)	This flag can be used for type testing.
.referenceNode : ReferenceBaseNode	Similar to ReferenceBaseNode#reference, an additional property references to the current node.
.referenceNode : ReferenceNode	Similar to ReferenceNode#reference, an additional property references to the current node.

Methods

Method	Description
.generateNodeType() : string	This method is overwritten since the node type is inferred from the uniform type of the reference node.
.generateNodeType() : string	This method is overwritten since the node type is inferred from the uniform type of the reference node.

Key Takeaways

1. ReferenceElementNode extends: EventDispatcher → Node → ArrayElementNode
2. Most relevant properties: isReferenceElementNode, isReferenceElementNode, referenceNode, referenceNode.
3. Key methods: generateNodeType, generateNodeType.
