Examples with LazyURIEncoder org.eclipse.xtext.linking.lazy.LazyURIEncoder used on opensource projects

Example 1 with LazyURIEncoder

use of org.eclipse.xtext.linking.lazy.LazyURIEncoder in project xtext-core by eclipse.

the class DefaultReferenceDescriptionTest method createResourceDescription.

protected IResourceDescription createResourceDescription(Resource testResource) {
    DefaultResourceDescriptionStrategy strategy = new DefaultResourceDescriptionStrategy();
    strategy.setQualifiedNameProvider(new IQualifiedNameProvider.AbstractImpl() {

        @Override
        public QualifiedName getFullyQualifiedName(EObject obj) {
            String name = SimpleAttributeResolver.NAME_RESOLVER.apply(obj);
            return (name != null) ? QualifiedName.create(name) : null;
        }
    });
    strategy.setLazyURIEncoder(new LazyURIEncoder());
    IResourceDescription resourceDescription = new DefaultResourceDescription(testResource, strategy);
    return resourceDescription;
