CancelGetContext()

voidCancelGetContext()
Cancel get context / get context list / get global contexts
Since
2.8

ConstructL()

voidConstructL()[private]

Symbian constructor

Since
2.8

DeleteContext(MNssDeleteContextClient *, MNssContext *)

TInt DeleteContext(MNssDeleteContextClient *aContextClient,
MNssContext *aContext
)
DeleteContext is called to remove a context from the VAS DB. This method is asynchronous. A call back will be made to either DeleteContextCompleted() or DeleteContextFailed() as defined in the MNssDeleteContextClient interface. It also returns an error code validating success of call to VAS DB.
Since
2.8

Parameters

MNssDeleteContextClient * aContextClient- call back address
MNssContext * aContext- context object to delete

DoCancel()

voidDoCancel()[virtual]
Look at CActive documentation for exaplanation. CActive
Since
2.8

GetContext(MNssGetContextClient *, const TDesC &)

TInt GetContext(MNssGetContextClient *aContextClient,
const TDesC &aName
)
GetContext is called to retrieve a context from the VAS DB. This method is asynchronous. A call back will be made to either GetContextCompleted() or GetContextFailed() as defined in the MNssGetContextClient interface. It also returns an error code validating success of call to VAS DB.
Since
2.8

Parameters

MNssGetContextClient * aContextClient- call back address
const TDesC & aName- name of context to retreive

GetContextList(MNssGetContextClient *)

TInt GetContextList(MNssGetContextClient *aContextClient)
GetContextList is called to retrieve a context list from the VAS DB. This method is asynchronous. A call back will be made to either GetContextListCompleted() or GetContextFailed() as defined in the MNssGetContextClient interface. It also returns an error code validating success of call to VAS DB.
Since
2.8

Parameters

MNssGetContextClient * aContextClient- call back address

GetGlobalContexts()

TMNssContextList *GetGlobalContexts()
GetGlobalContexts is called to get the list of global contexts in VAS DB. This method is synchronous (It used to be asynchronous before 2.8. A call back was made to either GetGlobalContextsCompleted() or GetContextFailed() as defined in the MNssInterCompContextMgrClient interface. It also returned an error code validating success of call to VAS DB). This method is for use by internal VAS components.
Since
2.8

Call back function from SRS DB, through interface MNssCoreSrsDBEventHandler Called after deleting from SRS DB is successful
Since
2.8

HandleSaveSrsDBCompleted()

voidHandleSaveSrsDBCompleted()
Call back function from SRS DB, through interface MNssCoreSrsDBEventHandler Called after saving to SRS DB is successful
Since
2.8
