Examples with MethodType java.lang.invoke.MethodType used on opensource projects

Example 91 with MethodType

use of java.lang.invoke.MethodType in project jdk8u_jdk by JetBrains.

the class MethodHandleConstants method testCase.

private static void testCase(MethodHandle mh, Class<?> defc, String name, Class<?> rtype, Class<?>... ptypes) throws Throwable {
    System.out.println(mh);
    // we include defc, because we assume it is a non-static MH:
    MethodType mt = methodType(rtype, ptypes);
    assertEquals(mh.type(), mt);
// FIXME: Use revealDirect to find out more
}

Example 92 with MethodType

public void testHashCode() {
    System.out.println("hashCode");
    MethodType instance = mt_viS;
    ArrayList<Class<?>> types = new ArrayList<>();
    types.add(instance.returnType());
    types.addAll(instance.parameterList());
    int expResult = types.hashCode();
    int result = instance.hashCode();
    assertEquals(expResult, result);
}

    for (int i = 0; i < instances.length; i++) {
        MethodType instance = instances[i];
        String result = instance.toString();
