chrono::ChClassFactory Class Reference

Description

A class factory.

It can create C++ objects from their string name. Just use the ChClassFactory::create() function, given a string. NOTE: desired classes must be previously registered via the CH_FACTORY_REGISTER macro, or using ClassRegister, otherwise the ChClassFactory::create() throws an exception. NOTE: You do not need to explicitly create it: a static ChClassFactory class factory is automatically instanced once, at the first time that someone registers a class. It is consistent also across different DLLs.

Member Function Documentation

ClassRegister()

static void chrono::ChClassFactory::ClassRegister ( const std::string &  keyName, ChClassRegistrationBase *  mregistration  )

inlinestatic

Register a class into the global class factory.

Provide an unique name and a ChClassRegistration object. If multiple registrations with the same name are attempted, only one is done.

ClassUnregister()

static void chrono::ChClassFactory::ClassUnregister ( const std::string &  keyName )

inlinestatic

Unregister a class from the global class factory.

Provide an unique name.

create() [1/2]

template<class T >

static void chrono::ChClassFactory::create ( const std::string &  keyName, ChArchiveIn &  marchive, T **  ptr  )

inlinestatic

Create from class name, for registered classes.

Name is the mnemonic tag given at registration. If a static T* ArchiveINconstructor(ChArchiveIn&) function is available, call it instead. The created object is returned in "ptr"

create() [2/2]

template<class T >

static void chrono::ChClassFactory::create ( const std::string &  keyName, T **  ptr  )

inlinestatic

Create from class name, for registered classes.

Name is the mnemonic tag given at registration. The created object is returned in "ptr"

GetClass()

static ChClassRegistrationBase* chrono::ChClassFactory::GetClass ( const std::string &  keyName )

inlinestatic

Get class registration info from class name.

Name is the mnemonic tag given at registration. Return nullptr if not registered.

GetClassTagName()

static std::string& chrono::ChClassFactory::GetClassTagName ( const std::type_info &  mtype )

inlinestatic

Tell the class name, from type_info.

This is a mnemonic tag name, given at registration, not the typeid.name().
