### Question:
LongAccessor implements PropertyAccessor<Long> { @Override public Long getCopy(Object object) { return object != null ? (Long) object : null; }  @Override final Long fromBytes(Class targetClass, byte[] bytes); @Override final byte[] toBytes(Object object); @Override final String toString(Object object); @Override Long fromString(Class targetClass, String s); @Override Long getCopy(Object object); Long getInstance(Class<?> clazz);  }### Answer:
@Test public void testGetCopy() { Long d1 = new Long(4); Long d2 = accessor.getCopy(d1); Assert.assertEquals(d1, d2); }
