Detailed Description

template<class Archive, class T>
struct cereal::detail::OutputBindingCreator< Archive, T >

Creates a binding (map entry) between an output archive type and a polymorphic type.

Bindings are made when types are registered, assuming that at least one archive has already been registered. When this struct is created, it will insert (at run time) an entry into a map that properly handles casting for serializing polymorphic objects

Member Function Documentation

savePolymorphicSharedPtr() [1/2]

template<class Archive , class T >

static void cereal::detail::OutputBindingCreator< Archive, T >::savePolymorphicSharedPtr ( Archive &  ar, T const *  dptr, std::false_type    )

inlinestatic

Does the actual work of saving a polymorphic shared_ptr.

This function will properly create a shared_ptr from the void * that is passed in before passing it to the archive for serialization.

This version is for types that do not inherit from std::enable_shared_from_this.

Parameters

ar	The archive to serialize to
dptr	Pointer to the actual data held by the shared_ptr

savePolymorphicSharedPtr() [2/2]

template<class Archive , class T >

static void cereal::detail::OutputBindingCreator< Archive, T >::savePolymorphicSharedPtr ( Archive &  ar, T const *  dptr, std::true_type    )

inlinestatic

Does the actual work of saving a polymorphic shared_ptr.

This function will properly create a shared_ptr from the void * that is passed in before passing it to the archive for serialization.

In addition, this will also preserve the state of any internal enable_shared_from_this mechanisms

Parameters

ar	The archive to serialize to
dptr	Pointer to the actual data held by the shared_ptr
