Detailed Description

template<class T>
class cereal::detail::StaticObject< T >

A static, pre-execution object.

This class will create a single copy (singleton) of some type and ensures that merely referencing this type will cause it to be instantiated and initialized pre-execution. For example, this is used heavily in the polymorphic pointer serialization mechanisms to bind various archive types with different polymorphic classes

Note

This function returns an object that holds a lock for this StaticObject that will release its lock upon destruction. This call will block until the lock is available.
