CObexTransportControllerBase Class Reference

class CObexTransportControllerBase : public CBase

Abstraction for transport controller implementations. Defines an interface to be used by Obex protocol layer as the facade to the transport layer.

In a concrete transport controller's NewL, the following things must be done: (a) CObexTransportControllerBase::iConnector must be assigned to a CObexConnector-derived type. (This may be reliant on the TObexTransportInfo object passed in at this time.) iConnector is owned by CObexTransportControllerBase . (b) CObexTransportControllerBase::iTransportInfo must be assigned to a persistent (i.e. heap-based) TObexTransportInfo or derived type. The derived transport controller may cast the TObexTransportInfo given at construction time to a known derived type and copy the data from it to the new instance on the heap. Note that ownership of the given TObexTransportInfo *remains with the client*. iTransportInfo is then owned by CObexTransportControllerBase .

In a concrete transport controller's NewTransportL, two instances of types derived from CObexActiveRW must be created, and stored in CObexTransportControllerBase::iActiveReader and CObexTransportControllerBase::iActiveWriter . CObexTransportControllerBase owns these.

const [private, pure virtual]

DoProcess(CObexPacket &)

IMPORT_C void

DoProcess

(

aPacket

)

[protected, virtual]

Process a Packet. Upcall to the owner

Parameters

)

[private, pure virtual]

Parameters

This function is part of the extension pattern and must be implemented by all derived instantiable classes. By default this returns null. Any derived class that is required to extend its interface and that of this base class returns its new interface in the form of an M class, that it extends, if and only if the corresponding TUid , aUid, is received. Otherwise the function calls the base class implementation, returning NULL.

Parameters
