I am calling EXPENSIVE check programmatically on resource.
Side effect is that, I loose all the error, warning and info markers, which are set through FAST and NORMAL checks.

Is there a way to get all the resource issues.
I will collect the issues and then I will call expensive check on resource.

Have a look at

org.eclipse.xtext.ui.editor.handler.ValidateActionHandler

the mode you have to use is CheckMode.ALL

First of all thanks Mr. DietrichFriend for reply.

Actually, In my project, Fast and Normal checks are done with editor touch and save.
In my project, I need to call cross reference checks through Expensive check. So I want to retrieve all the issues in resource before calling expensive check.

In my project using CheckMode.ALL callls the validation two times. Once when I save resource and second time at the place where i am calling expensive check.

The following could work:
1) create your own subclass of MarkerIssueProcessor and in processIssues pass only 'MarkerTypes.EXPENSIVE_VALIDATION' to the constructor of the AddMarkersOperation
2) Use this subclass in your own subclass of ValidateActionHandler
3) Bind your handler instead of the default.

List<Issue> projectIssues = new ArrayList<>();
for (Resource resource : loadAllResourcesFromBuildContext(context, delta)) {
List<Issue> resourceIssues = crossReferenceValidator.validate(resource, CheckMode.EXPENSIVE_ONLY,
CancelIndicator.NullImpl);
projectIssues.addAll(resourceIssues);
}

public List<Issue> validate(Resource resource, CheckMode mode, CancelIndicator mon) throws OperationCanceledError {
List<Issue> issues = new ArrayList<>();
EcoreUtil.resolveAll(resource);
issues.addAll(collectNormalAndFastIssues(resource));

LOGGER.info("Validating cross references...");

issues.addAll(super.validate(resource, mode, mon));
return issues;
}

I know this is not efficient as Normal and Fast checks gets called twice. But it works as of now. I am finding better approach also.
