pimpl

Container for an unknown object. It stores a pointer to an object and its destructor. Pimpl can be used to hide includes from the main model to speed up compile time.
Nameabmt::util::pimpl
Header#include <abmt/util/pimpl.h>

Attributes
void* p
std::function<void()> destruct
std::size_t tid

Methods
pimpl()=default
pimpl(T* instance)
pimpl(const pimpl& p)=delete
void set(T* instance)Sets a new pointer with a new type. When it was set before the old object is deleted.
T& get()
bool is_type()template function
bool is_set()
T& get2()when you know what you are doing and what your past me has done... (returns cast without type-check)
~pimpl()

default_ptr < typename T >

A std::shared_ptr with default initialization of T.
Nameabmt::default_ptr
Header#include <abmt/util/default_ptr.h>

Methods
default_ptr()
default_ptr(T* p)
default_ptr(T2* p)
default_ptr(const std::shared_ptr< T2 >& p)
