claw::math::coordinate_2d< U > claw::math::coordinate_2d< T >::cast_value_type_to | ( | ) | const [inline] |
Get a copy of the rectangle by converting its members to a given type.
Consider the following code:
coordinate_2d<float> a;
...
coordinate_2d<int> b(a);
The copy constructor will be called, and your compiler should print some warnings in your console. These warnings have a meaning, so we don't wan't to make them disapear by adding explicit type conversion inside the coordinate_2d class nor adding a cast operator that will be used silently by the compiler.
If you really want to convert the type, this method will explicitly cast the member variables.
