It is better to use boost::polymorphic_cast instead of … WebThe most general cast supported by most of the C++ compilers is as follows −. (type) expression. Where type is the desired data type. There are other casting operators supported by C++, they are listed below −. const_cast (expr) − The const_cast operator is used to explicitly override const and/or volatile in a cast. WebBoost.DynamicAny. Boost.DynamicAny is a vairant on Boost.Any which provides more flexible dynamic casting of the underlying type. Whereas retreiving a value from Boost.Any requires that you know the exact type stored within the Any, Boost.DynamicAny allows you to dynamically cast to either any base of the held type..

WebTypical solutions feature the dynamic-allocation of objects, which are subsequently manipulated through a common base type (often a virtual base class or, more dangerously, a void*). Objects of concrete type may be then retrieved by way of a polymorphic downcast construct (e.g., dynamic_cast, boost::any_cast, etc.).
