Class that handle C++ values of generic type using type erasure and functors.

For example used to call the ArchiveOUT function for unrelated classes that implemented them. This helps stripping out the templating, to make ChArchiveOut easier and equippable with virtual functions.

#include <ChArchive.h>

Inherited by chrono::ChValueSpecific< TClass >.

Member Function Documentation

◆ CallArchiveOutConstructor()

virtual void chrono::ChValue::CallArchiveOutConstructor ( ChArchiveOut marchive)
pure virtual

Use this to call (optional) member function ArchiveOUTconstructor.

This is expected to serialize constructor parameters if any. If ArchiveOUTconstructor is not provided, simply does nothing.

◆ GetClassRegisteredName()

virtual std::string& chrono::ChValue::GetClassRegisteredName ( )
pure virtual

Get registered name in class factory.

If type is not previously registered, returns a "" string. This is platform-independent.

◆ PointerUpCast()

template<typename U >
U* chrono::ChValue::PointerUpCast ( )

Use this to do safe dynamic cast.

This uses the cast/throw trick for dynamic cast after type-erasure; note that this has performance penalty respect to usual dynamic_cast<>, which is not possible here. Note: can only upcast, but no downcast (i.e. U must be higher the TClass used when instantiating ChValueSpecific); otherwise use a later dynamic_cast<>.
