How do i convert a to type test::a?
There are rules about casting pointers, a number of which are in clause 6.3.2.3 of the c 2011 standard
Among other things, pointers to objects may be cast to other pointers to objects and, if converted back, will compare equal to the original. 2 your problem is not the lack of dynamic casting Casting integer to double isn't possible at all You seem to want to give java an object of one type, a field of a possibly incompatible type, and have it somehow automatically figure out how to convert between the types.
6 do you understand the concept of casting Casting is the process of type conversion, which is in java very common because its a statically typed language 'casting' with reflection asked 16 years, 1 month ago modified 4 years, 6 months ago viewed 65k times For example, casting using 4294967295us as u32 works and the rust 0.12 reference docs on type casting say a numeric value can be cast to any numeric type
A raw pointer value can be cast to or from any integral type or raw pointer type
Any other cast is unsupported and will fail to compile. Casting to object is unsafe Why do you want to do so Not sure if it's relevant, you can use instanceof to check the class of the object.
Casting has sense only for a variable (= chunk of memory whose content can change) there are no variables whose content can change, in python There are only objects, that aren't contained in something They have per se existence Then, the type of an object can't change, afaik
Then, casting has no sense in python
