createNodeLink#decodePickElement¶
This page documents the NodeLink.decodePickElement method.
Summary¶
createNodeLink#decodePickElement maps a picking element index back to either a node or an edge. Element indices map to nodes first, then to edges.
That means 0 .. NodeLink.nodeCount - 1 resolve to nodes, and the next NodeLink.edgeCount element indices resolve to edges.
Syntax¶
NodeLink.decodePickElement(elementIndex: number): { component: "node" | "edge"; componentIndex: number } | null
const decoded = nodeLink.decodePickElement(elementIndex);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
elementIndex |
number |
Yes | Picking element index to decode back into node or edge space. |
Returns¶
{ component: "node" | "edge"; componentIndex: number } | null - Decoded component kind and component index, or null when the element index is out of range.
