### Question:
TransformedGenerator extends LoopGenerator<E> { @Override public int hashCode() { int result = "TransformedGenerator".hashCode(); result <<= 2; Generator<?> gen = getWrappedGenerator(); result ^= gen.hashCode(); result <<= 2; result ^= func.hashCode(); return result; } @SuppressWarnings("unchecked")  TransformedGenerator(Generator<? extends I> wrapped, Function<? super I, ? extends E> func); @SuppressWarnings("unchecked") void run(final Procedure<? super E> proc); @Override boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testHashcode() { assertEquals(sumsTwoGenerator.hashCode(), sumsTwoGenerator.hashCode()); assertEquals(sumsTwoGenerator.hashCode(), new TransformedGenerator<Integer, Integer>(wrappedGenerator, sumsTwo).hashCode()); }
