CUpnpSymbianServerBase Class Reference

class CUpnpSymbianServerBase : public CServer2

Base class for all symbian server classes used in upnp stack project This implementation provides:

proper server starting,
2 seconds stoping timeout,
stopping server if ( no connected clients && CanBeStopped() ) CanBeStopped() SuggestShutdown()
session connection version checking,
basic panics utility functions,
basic errors handling Note that it should be used with client part implementation that use RUpnpSessionBase class.

Member Functions Documentation

BaseConstructL()

IMPORT_C void

BaseConstructL

(

)

[protected]

Second phase base constructor. It must be called by derived class.

CanBeStopped()

IMPORT_C TBool

CanBeStopped

(

)

const [private, virtual]

Derived classes can implement in the method additional condidions of stopping server process that will be checked in SuggestShutdown method and befor actual server stopping. Default implementation provides no additional condidions.

DecrementSessionCount()

void

DecrementSessionCount

(

)

[private]

Decrement the count of the active sessions for this server.

IncrementSessionCount()

void

IncrementSessionCount

(

)

[private]

Increment the count of the active sessions for this server.

NewSessionL(const RMessage2 &)

CSession2 *

NewSessionL

(

const RMessage2 &

aMessage

)

const [private, pure virtual]

Returns new CSession2 object. This method don't have to bother about version checking as this is done by implementation of CUpnpSymbianServerBase::NewSessionL (const TVersion & aVersion, const RMessage2 & aMessage) that is wrapping this method.

Parameters

const RMessage2 & aMessage

NewSessionL(const TVersion &, const RMessage2 &)

IMPORT_C CSession2 *	NewSessionL	(	const TVersion &	aVersion,
			const RMessage2 &	aMessage
		)	const [protected, virtual]

This method wraps pure virtual NewSessionL(const RMessage2&) and leaves with KErrNotSupported if aVersion is different from version provided by pure virtual SupportedVersion.

Parameters

const TVersion & aVersion
const RMessage2 & aMessage

PanicClient(const RMessage2 &, TInt)

IMPORT_C void	PanicClient	(	const RMessage2 &	aMessage,
			TInt	aReason
		)	const

Panic the client.

Parameters

const RMessage2 & aMessage	the message channel to the client.
TInt aReason	the reason code for the panic.

PanicServer(TInt)

IMPORT_C void

PanicServer

(

TInt

aPanic

)

const [protected]

Panic the server.

Parameters

TInt aPanic

the panic code.

RunError(TInt)

IMPORT_C TInt

RunError

(

TInt

aError

)

[protected, virtual]

Process any errors.

Parameters

TInt aError

the leave code reported.

RunL()

IMPORT_C void

RunL

(

)

[protected, virtual]

Invoked by active object framework to handle ending events

ServerName()

const TDesC &

ServerName

(

)

const [private, pure virtual]

Return name of a server.

StartServer(const TDesC &, TServerFactoryMethodLC)

IMPORT_C TInt	StartServer	(	const TDesC &	aThreadName,
			TServerFactoryMethodLC	aServerFactoryMethodLC
		)	[static]

Fully initialise thread, and start the server. Method is intended to be called from E32Main method without any earlier initialisation.

Parameters

const TDesC & aThreadName	name to which thread will be renamed.
TServerFactoryMethodLC aServerFactoryMethodLC	two phase constructor of server object that leaves it on cleanup stack.

StartServerL(const TDesC &, TServerFactoryMethodLC)

void	StartServerL	(	const TDesC &	aThreadName,
			TServerFactoryMethodLC	aServerFactoryMethodLC
		)	[private, static]

Internal method that initialises thread, and starts the server. Precondition is that cleanup stack is correctly initialised and method is called from within a TRAP.

Parameters

const TDesC & aThreadName	name to which thread will be renamed.
TServerFactoryMethodLC aServerFactoryMethodLC	two phase constructor of server object that leaves it on cleanup stack.

SuggestShutdown()

IMPORT_C void

SuggestShutdown

(

)

[protected]

Method should be called when derived class wants to suggest closing of the media server. This method checks every stop condidion and starts closing server timeout if all of them are fulfilled.
