For my project I am introducing new method in language server context. I need to get allready build xtext resource set so that i need not to load resource again.

When the first build happen request method 'initialize' i see projectManager ResourceSet is populated. I just want to reuse xtext resource so i injected ProjectManager in my class but projectManager.getResourceSet() always return null.

@Inject
ProjectManager projectManager;

@JsonRequest(value = "UpdateModel")
@Override
public CompletableFuture<?> request(InitializeParams parameter) {

ResourceSet myResource =projectManager.getResourceSet(); // returns  resourceSet null

}



Looking forward to here from you.

I am not sure if this is the correct way of doing what you want to achieve
Is there a reason you don't call requestmanager runread or runwrite methods as other services do

@ Christian Dietrich

Thank you for your quick reply.

To Answer your questions I just implemented ILanguageServerExtension and made changes according to that. I was able to achieve new method functionality(Update Model). I just want to optimize this further(if xtext resource already build just use it, instead of loading again).

tried : Once I have IlanguageServerAceess i tried to create ResourceSet based on URI ilanguageServerAceess.newLiveScopeResourceSet(uri); // Resource set got created but no resource added.

I have gone through runRead method If my understanding is correct runRead method work for particular resource and its adding request to queue(ExecutorService).

What I am trying to achieve is get all resource and update model and save.

@JsonRequest(value = "UpdateModel")
@Override
public CompletableFuture<?> request(InitializeParams parameter) {

ResourceSet myResource =projectManager.getResourceSet(); // returns resourceSet null

}
