Detailed Description

An adapter factory defines behavioral extensions for one or more classes that implements the IAdaptable interface. Adapter factories are registered with an adapter manager.

This interface can be used without OSGi running.

Clients may implement this interface.

Member Function Documentation

virtual Object* berry::IAdapterFactory::GetAdapter ( IAdaptable *  adaptableObject, const std::string &  adapterType  )

pure virtual

Returns an object which can be cast to the given adapter type and which is associated with the given adaptable object. Returns 0 if no such object can be found.

A typical implementation would look like this:

void* GetAdapter(void* adaptableObject, const std::type_info& adaptableType, const std::string& adapterType) { if (Image* img = CastHelper<Image>(adaptableObject, adaptableType)) { if (adapterType == "berry::IResource") { return new IResource(img->GetPath()); } } return 0; }

Parameters

adaptableObject	the adaptable object being queried (usually an instance of IAdaptable)
adaptableType	the type information for the adaptable object
adapterType	the type of adapter to look up

Returns

a object castable to the given adapter type, or 0 if this adapter factory does not have an adapter of the given type for the given object

virtual void berry::IAdapterFactory::GetAdapterList ( std::vector< const std::type_info & > &  adapters )

pure virtual

Returns the collection of adapter types handled by this factory.

This method is generally used by an adapter manager to discover which adapter types are supported, in advance of dispatching any actual getAdapter requests.

Returns

the collection of adapter types
