ioc-cpp

Inversion of control/dependency injection container for C++03.

Usage:

#include <ioccpp/ioc.h>
...
// in composition root/assembler
IoCContainer<IPerson>::Register(boost::make_shared<Developer>());
...
// later in code
IPerson& person = IoCContainer<IPerson>::Resolve();

or, alternatively, use a factory function for lazy initialization/getting copies:

#include <ioccpp/ioc.h>
...
boost::shared_ptr<IPerson> developerFactory() { return boost::make_shared<Developer>(); }
...
IoCContainer<IPerson>::RegisterFactory(developerFactory);
...
IPerson& person = IoCContainer<IPerson>::Resolve();
boost::shared_ptr<IPerson> newPerson = IoCContainer<IPerson>::ResolveNew();

Note that you must create the symobol for each interface as follows:

// in IocContainterIPerson.cpp
#include "Persons.h"
#include <ioccpp/IoCContainerImpl.hh>

template class IoCContainer<IPerson>;
