Detailed Description

General purpose factory for RefObject. Create or Bind to a real object, based on a string specification. A RefFactory must be instantiated once : it is usually done with a single static declaration in the source file, as the factory constructor is responsible for adding itself to a global list of factories (factory_list_ in AutoRef.cpp).

Todo:

is bind method really useful

Member Function Documentation

AutoRefBase RefFactory::bind ( const AChar *  s ) const

virtual

Bind to an existing object, from a string spec. Must return NULL if the spec is not handled by this factory.

Todo:

is this method useful

AutoRefBase RefFactory::create ( const AChar *  s ) const

virtual

Create an object from a string specification. If this specific factory is not intended to handle instantiation for this spec, it must return NULL.

Parameters

s	optional creation parameter

Returns

an autoref to a created object

Reimplemented in SenderFactoryTCPIP, ListenerFactoryTCPIP, SenderFactorySHM, and ListenerFactorySHM.

const AChar * RefFactory::factory_name ( ) const

virtual

Name of the type this factory claims to be able to instanciate. This factory is a pretender for the creation of RefObjects which have the same factory_name.

Returns

factory name

Reimplemented in SenderFactoryTCPIP, ListenerFactoryTCPIP, SenderFactorySHM, and ListenerFactorySHM.

AutoRefBase RefFactory::lookup_bind ( const AChar *  factory_name, const AChar *  s, const AutoRefBase &  def  )

static

Same as lookup_create, but for binding.

Todo:

is useful

AutoRefBase RefFactory::lookup_create ( const AChar *  factory_name, const AChar *  s, const AutoRefBase &  def  )

static

Check all the factories in the global list, to instantiate an object of type 'factory_name', with spec 's'. Return the instantiated object, or 'def' (the given default object) if no factory was able to create the object.

Returns

an autoref to a created object

Parameters

factory_name	name of a factory
s	optional creation parameter
def	default value
