ExpressionNode

Source: packages/parametric/src/nodes/ExpressionNode.ts

Properties

Name	Type	Description
`expression`	`string`	The raw JS expression string that this node evaluates.
`ownerNodes`	`{ evaluate: () => void; } \| undefined`	The owning node collection (the ModelScope's `nodes`), or undefined when this expression isn't mounted under an owner yet. UI uses this only to re-evaluate the graph after an edit (see `requestEvaluate`).

Signature	Description
`setInput(expr: string): void`	Update the expression string and propagate dirty flags to all dependents.
`buildContext(): EvalContext`	Public eval scope for this expression (the same scope `compute()` uses).
`requestEvaluate(): void`	Re-evaluate the whole owning graph. Called by the UI after it writes a new expression (field blur / array row edit) so dependent nodes + geometry refresh. No-op when not yet mounted under an owner.
