Detailed Description

template<class E>
class commore::AutoRef< E >

AutoRef is a smart pointer on RefObject objects. AutoRef is templatized with the type of the pointed object (a class which publicly inherits from RefObject). In Commore, an AutoRef<MyType> is usually typedefed as PMyType. An AutoRef can be used in many ways.

It can be used as a pointer to a RefObject, for reference counting : class A : public RefObject; typedef AutoRef PA; A a; PA pa(a);

It can be used as an way to instantiate its pointed object, implicitly using a factory under the hood : class A : public RefObject { static AChar* factory_name() {return "A";} } typedef AutoRef PA; class AFactory : public RefFactory { AutoRefBase create(AChar* s) const { // instantiate an A object, based on the // specification given by s. Return NULL if // this factory is not the right one for this task. const AChar* factory_name() const {return "A";} }; static AFactory a_factory_; // instantiate this factory and add it to the list of global factories

It is used in this way : PA pa; pa.create("instantiation specification, understandable by the factory");

This is useful when many factories claim to instantiate the same type of object (ie, factories which factory_name is the same as RefObject's factory_name). Each of these factories being able to instantiate an object depending on the demanded spec : each one will be tested until one accepts to perform the instantiation.

The template class E must have the static methods auto_create, create, bind and factory_name.
