Example 1 with IResourceScopeCache

use of org.eclipse.xtext.util.IResourceScopeCache in project n4js by eclipse.

the class N4JSResource method updateInternalState.

/**
 * Overridden to make sure that we add the root AST element sneakily to the resource list to make sure that no
 * accidental proxy resolution happens and that we do not increment the modification counter of the contents list.
 */
@Override
protected void updateInternalState(IParseResult newParseResult) {
    setParseResult(newParseResult);
    EObject newRootAstElement = newParseResult.getRootASTElement();
    if (newRootAstElement != null && !getContents().contains(newRootAstElement)) {
        // do not increment the modification counter here
        sneakyAddToContent(newRootAstElement);
    }
    reattachModificationTracker(newRootAstElement);
    clearErrorsAndWarnings();
    addSyntaxErrors();
    doLinking();
    // make sure that the cache adapter is installed on this resource
    IResourceScopeCache cache = getCache();
    if (cache instanceof OnChangeEvictingCache) {
        ((OnChangeEvictingCache) cache).getOrCreate(this);
    }
}

Example 2 with IResourceScopeCache

use of org.eclipse.xtext.util.IResourceScopeCache in project dsl-devkit by dsldevkit.

the class NodeModelHandler method insertProxyModel.

/**
 * {@inheritDoc}

@Override
public void insertProxyModel() {
    // Node model can be accessed by:
    // 1. checking the adapters of an EObject
    ICompositeNode rootNode = null;

        if (rootNode == null) {
            rootNode = node;
        }
    }
    // 2. fetching the ParseResult instance of the Resource
    EObject emfRootObject = resource.getContents().isEmpty() ? null : resource.getContents().get(0);
    resource.setParseResult(new ParseResult(emfRootObject, rootNode, false));
    // Add cache now, otherwise it will trigger model inference later.
    IResourceScopeCache cache = resource.getCache();
    if (cache instanceof OnChangeEvictingCache) {
        ((OnChangeEvictingCache) cache).getOrCreate(resource);
    }
}

Example 3 with IResourceScopeCache

use of org.eclipse.xtext.util.IResourceScopeCache in project xtext-core by eclipse.

the class DerivedStateAwareResource method updateInternalState.

/**
 * Overridden to make sure that the cache is initialized during {@link #isLoading() loading}.

    IResourceScopeCache cache = getCache();
    if (cache instanceof OnChangeEvictingCache) {
        ((OnChangeEvictingCache) cache).getOrCreate(this);
    }
}

Example 4 with IResourceScopeCache

use of org.eclipse.xtext.util.IResourceScopeCache in project dsl-devkit by dsldevkit.

the class BugAig1084 method recursiveLookUp.

/**
