- 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)
- c# - Direct casting vs as operator? - Stack Overflow
Custom implicit explicit casting: Usually a new object is created Value Type Implicit: Copy without losing information Value Type Explicit: Copy and information might be lost IS-A relationship: Change reference type, otherwise throws exception Same type: 'Casting is redundant' It feels like the object is going to be converted into
- Casting variables in Java - Stack Overflow
Casting in Java isn't magic, it's you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn't have had otherwise
- java: How can I do dynamic casting of a variable from one type to . . .
Casting of an object does NOT change anything; it is just the way the compiler treats it The only reason to do something like that is to check if the object is an instance of the given class or of any subclass of it, but that would be better done using instanceof or Class isInstance()
- sql - datetime Cast or Convert? - Stack Overflow
What to choose: Cast or Convert for datetimes (Microsoft SQL Server)? I have had a look at the MSDN Specifications At the first glance it seems there is no difference, except for the syntax: Synt
- What are the rules for casting pointers in C? - Stack Overflow
Casting pointers is usually invalid in C There are several reasons: Alignment It's possible that, due to alignment considerations, the destination pointer type is not able to represent the value of the source pointer type For example, if int * were inherently 4-byte aligned, casting char * to int * would lose the lower bits Aliasing
- 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 The method may be defined in the parent class and overriden in the child class This can also be done if the method only exists in the child
- What exactly is a type cast in C C++? - Stack Overflow
Not only that, but it offers more restrictive explicit casts, such as static_cast, dynamic_cast, reinterpret_cast, and const_cast, each of which further restricts the explicit cast to only a subset of possible conversions, reducing the potential for casting errors
