Example 91 with VariableElement

use of javax.lang.model.element.VariableElement in project j2objc by google.

the class OuterReferenceResolverTest method testNestedLocalClassesWithNestedCreations.

public void testNestedLocalClassesWithNestedCreations() {
    // This test is particularly tricky for OuterReferenceResolver because A captures variable i,
    // but that is not known until after A's creation. A's creation occurs within B, which requires
    // B to have an outer field in order to access A's capturing field for i. B's creation therefore
    // requires the outer field to be passed as an outer argument.
    // Because of the cascading effects of the statements in this test and the order in which they
    // occur, we would need to do three passes over the code to resolve B's creation successfuly.
    resolveSource("Test", "class Test { void test(int i) { class A { " + "void foo() { class B { void bar() { new B(); new A(); } } } " + "int other() { return i; } } } }");
    ClassInstanceCreation bCreate = (ClassInstanceCreation) nodesByType.get(Kind.CLASS_INSTANCE_CREATION).get(0);

    assertTrue(outerArg instanceof SimpleName);
    VariableElement var = TreeUtil.getVariableElement(outerArg);
