| 19 | // Overview: |
Dan Albert | 1d4a1ed | 2016-05-25 22:36:09 -0700 | [diff] [blame^] | 20 | // Bullets 1 and 2 handle the case where 'f' is a pointer to member function. |

Dan Albert | 1d4a1ed | 2016-05-25 22:36:09 -0700 | [diff] [blame^] | 22 | // type derived from 'T'. Bullet 2 handles all other cases. |
Eric Fiselier | 48aa2cf | 2015-07-28 01:25:36 +0000 | [diff] [blame] | 23 | // |
| 24 | // Concerns: |
| 25 | // 1) cv-qualified member function signatures are accepted. |
| 26 | // 2) reference qualified member function signatures are accepted. |
| 27 | // 3) member functions with varargs at the end are accepted. |
| 28 | // 4) The arguments are perfect forwarded to the member function call. |
| 29 | // 5) Classes that are publicly derived from 'T' are accepted as the call object |
| 30 | // 6) All types that dereference to T or a type derived from T can be used |
| 31 | // as the call object. |
| 32 | // 7) Pointers to T or a type derived from T can be used as the call object. |
| 33 | // 8) Reference return types are properly deduced. |
| 34 | // |
| 35 | // |
| 36 | // Plan: |
| 37 | // 1) Create a class that contains a set, 'S', of non-static functions. |
| 38 | // 'S' should include functions that cover every single combination |
| 39 | // of qualifiers and varargs for arities of 0, 1 and 2 (C-1,2,3). |
| 40 | // The argument types used in the functions should be non-copyable (C-4). |
| 41 | // The functions should return 'MethodID::setUncheckedCall()'. |
| 42 | // |
| 43 | // 2) Create a set of supported call object, 'Objs', of different types |
| 44 | // and behaviors. (C-5,6,7) |
| 45 | // |
| 46 | // 3) Attempt to call each function, 'f', in 'S' with each call object, 'c', |
| 47 | // in 'Objs'. After every attempted call to 'f' check that 'f' was |
| 48 | // actually called using 'MethodID::checkCalled(<return-value>)' |
| 49 | // |
| 50 | // 3b) If 'f' is reference qualified call 'f' with the properly qualified |
| 51 | // call object. Otherwise call 'f' with lvalue call objects. |
| 52 | // |
| 53 | // 3a) If 'f' is const, volatile, or cv qualified then call it with call |
| 54 | // objects that are equally or less cv-qualified. |
