Custom parameter info

[noman-khan1224]

I want to fetch data, and I use the updateContent method for this purpose. However, within this method, there is a for loop that assigns an empty value to the node. If I remove this for loop from the updateContent method, will it cause any performance issues? Also, what is the purpose of this for loop?

Request you to help with an approach for same?

Hey @noman-khan1224,

you seem to be using an outdated version of Langium. We no longer clear the exported node of an AstNodeDescription:

langium/packages/langium/src/workspace/index-manager.ts

Lines 154 to 160 in 6971c83

	async updateContent(document: LangiumDocument, cancelToken = CancellationToken.None): Promise<void> {
	const services = this.serviceRegistry.getServices(document.uri);
	const exports = await services.references.ScopeComputation.computeExports(document, cancelToken);
	const uri = document.uri.toString();
	this.symbolIndex.set(uri, exports);
	this.symbolByTypeIndex.clear(uri);
	}

The purpose used to be to reduce our memory footprint by deleting references to elements that have been potentially unloaded from the workspace. However, we no longer support that use case and so we also deleted the loop.
