Examples of NewInstanceMetaMethod

org.codehaus.groovy.runtime.metaclass.NewInstanceMetaMethod
A MetaMethod implementation where the underlying method is really a static helper method on some class but it appears to be an instance method on a class. This implementation is used to add new methods to the JDK writing them as normal static methods with the first parameter being the class on which the method is added. @author James Strachan @version $Revision: 8959 $

    public void testInvokeMetaMethod() throws Exception {
        Method method = getClass().getMethod("dummyMethod", new Class[]{String.class, String.class});

        Object answer = metaMethod.invoke("abc", new Object[]{"xyz"});
        assertEquals("def", answer);


        assertTrue("Should not appear as static method", !metaMethod.isStatic());
