Example 46 with Elements

use of javax.lang.model.util.Elements in project auto by google.

the class MoreTypesTest method asElement.

@Test
public void asElement() {
    Elements elements = compilationRule.getElements();
    TypeElement stringElement = elements.getTypeElement("java.lang.String");
    assertThat(MoreTypes.asElement(stringElement.asType())).isEqualTo(stringElement);
    TypeParameterElement setParameterElement = Iterables.getOnlyElement(compilationRule.getElements().getTypeElement("java.util.Set").getTypeParameters());
    assertThat(MoreTypes.asElement(setParameterElement.asType())).isEqualTo(setParameterElement);
// we don't test error types because those are very hard to get predictably
}
