Example 2 with ClassInstanceCreation

use of com.google.devtools.j2objc.ast.ClassInstanceCreation in project j2objc by google.

the class OuterReferenceResolverTest method testAnonymousClassCreatesLocalClassWithCaptures.

    resolveSource("Test", "class Test { Runnable test(final Object o) { " + "class Local { public void foo() { o.toString(); } } " + "return new Runnable() { public void run() { new Local(); } }; } }");

Example 3 with ClassInstanceCreation

use of com.google.devtools.j2objc.ast.ClassInstanceCreation 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);
    Expression outerArg = bCreate.getExpression();
    assertTrue(outerArg instanceof SimpleName);
    VariableElement var = TreeUtil.getVariableElement(outerArg);
    assertNotNull(var);
    assertEquals("this$0", ElementUtil.getName(var));

Example 5 with ClassInstanceCreation

use of com.google.devtools.j2objc.ast.ClassInstanceCreation in project j2objc by google.

the class EnumRewriter method addArcInitialization.

// ARC does not allow using "objc_constructInstance" so ARC code doesn't get
// the shared allocation optimization.

    List<Statement> stmts = node.getClassInitStatements().subList(0, 0);
    int i = 0;
    for (EnumConstantDeclaration constant : node.getEnumConstants()) {
