### Question:
ObjectXMLWriter implements MessageBodyWriter { @Override public boolean isWriteable(Class type, Type genericType, Annotation[] annotations, MediaType mediaType) { if (type.getName().equals("org.slc.sli.api.representation.Home") || type.getName().equals("org.slc.sli.api.representation.ErrorResponse")) { return true; } return false; }  @Override boolean isWriteable(Class type, Type genericType, Annotation[] annotations, MediaType mediaType); @Override long getSize(Object o, Class type, Type genericType, Annotation[] annotations, MediaType mediaType); @Override void writeTo(Object o, Class type, Type genericType, Annotation[] annotations, MediaType mediaType,
                        MultivaluedMap httpHeaders, OutputStream entityStream);  }### Answer:
@Test public void testIsWritable() { assertTrue(writer.isWriteable(ErrorResponse.class, null, null, null)); assertTrue(writer.isWriteable(Home.class, null, null, null)); assertFalse(writer.isWriteable(EntityResponse.class, null, null, null)); }
