Hi All. I modified boost::any to adapt noncopyable object. The boost::any can use noncopyable object like this: _____________________________________________________________ struct B : boost::noncopyable { B() : v1(), v2() {}; B(unsigned int value1, unsigned int value2) : v1(value1) ,v2(value2) {}; unsigned int v1, v2; }; BOOST_AUTO_TEST_CASE(test02) { any test; //test = B(); // compile error //test.reset<B>(10, 20); // compile error test.reset<B, false>(10, 20); //any test2(test); // throw //any test2; //test2 = test; // throw BOOST_CHECK_EQUAL(any_cast<B&>(test).v1, 10); BOOST_CHECK_EQUAL(any_cast<B&>(test).v2, 20); } _____________________________________________________________________ If you are interested in this, please see #2748 for detail. https://svn.boost.org/trac/boost/ticket/2748 Thanks, Nowake
