Constructor & Destructor Documentation

CFactoryContainer()

IMPORT_C

CFactoryContainer

(

)

[protected, explicit]

~CFactoryContainer()

IMPORT_C

~CFactoryContainer

(

)

Destructor - cleanup Factories (delete them all)

Member Functions Documentation

AddL(CFactoryBase &)

IMPORT_C void

AddL

(

CFactoryBase &

aFactory

)

[protected]

Add a factory to this container

Parameters

CFactoryBase & aFactory

Factory to be added to the container

Factory(TInt)

IMPORT_C CFactoryBase *

Factory

(

TInt

aIndex

)

const [protected]

Parameters

TInt aIndex

FetchNodeInterfaceControlL(TInt)

IMPORT_C NetInterfaces::TInterfaceControl *

FetchNodeInterfaceControlL

(

TInt

aInterfaceId

)

[virtual]

Iterates through all the held factories and asks them whether they implment the requested interface. As factory containers are not meant to be derived from, this implementation is an accepted deviation from the original semantics of FetchNodeInterfaceControlL.

Exceptions

Leaves

with KErrNotSupported if none of the factories implement the interface

NetInterfaces::TInterfaceControl

Parameters

TInt aInterfaceId

The id of the requested interface extension.

FindFactory(TUid)

IMPORT_C CFactoryBase *

FindFactory

(

TUid

aFactoryUid

)

const

Search this factory container for a factory with a matching id

Parameters

TUid aFactoryUid

Id of the factory the caller wishes to find

FindObject(MFactoryQuery &)

IMPORT_C AFactoryObject *

FindObject

(

MFactoryQuery &

aQuery

)

const [protected]

Parameters

MFactoryQuery & aQuery

RegisterNotifierL(TUid, const IFactoryNotify &)

IMPORT_C void	RegisterNotifierL	(	TUid	aFactoryUid,
			const IFactoryNotify &	aFactoryNotify
		)

Registers a callback for factory container notification

Exceptions

Leaves

with KErrArgument if the factory specified by aFactoryId is not found

IConnectionFactoryNotify

Parameters

TUid aFactoryUid	The Id of the factory that will be registered
const IFactoryNotify & aFactoryNotify	The IConnectionFactoryNotify object that implements the callback
