- Casting objects in Java - Stack Overflow
Casting can be used to clearly state that you are calling a child method and not a parent method So in this case it's always a downcast or more correctly, a narrowing conversion
- Regular cast vs. static_cast vs. dynamic_cast - Stack Overflow
Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type dynamic_cast Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy) dynamic_cast (expression)
- Why is casting a const reference directly to a mutable reference . . .
The superficial answer to the question "why?" is that these simply are the rules of as expressions in Rust Quoting from the Nomicon: Casting is not transitive, that is, even if e as U1 as U2 is a valid expression, e as U2 is not necessarily so With the as operator, you can either perform explicit coercions or casts There is neither a cast nor a coercion to go directly from u8 to *mut u8
- Whats the difference between casting and coercion in Python?
Cast really only comes up in the C FFI What is typically called casting in C or Java is referred to as conversion in python, though it often gets referred to as casting because of its similarities to those other languages In pretty much every language that I have experience with (including python) Coercion is implicit type changing
- What are the rules for casting pointers in C? - Stack Overflow
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
- c++ - When should static_cast, dynamic_cast, const_cast, and . . .
The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers
- Casting vs using the as keyword in the CLR - Stack Overflow
Could you add a small example of why you're using the casts in the first place to the question, or perhaps start a new one? I'm kinda interested in why you would need the cast for unit testing only I think it's outside of the scope of this question though
- Best practice in C++ for casting between number types
What is the best practice for casting between the different number types? Types float, double, int are the ones I use the most in C++ An example of the options where f is a float and n is a doubl
