Detailed Description

Class for managing SIP client transactions. It provides services for ending and getting the SIP client transaction parameters. Some client transactions can also be canceled.

The user of the class cannot instante this class.

Constructor & Destructor Documentation

CSIPClientTransaction ( MTransactionAssociation &, CSIPRefresh * )

Destructor

Member Function Documentation

CancelAllowed ( )

IMPORT_C TBool

CancelAllowed

(

)

const [virtual]

Checks if the client transaction is such that it can be cancelled. This does no check whether the transaction is currently in such a state that the canceling can be done now.

Returns: ETrue if client transaction can be cancelled; EFalse otherwise

CancelL ( )

IMPORT_C CSIPClientTransaction *

CancelL

(

)

Cancels client transaction i.e. creates a CANCEL request and sends it to the remote UA.

Pre-condition: State()==EProceeding
CancelAllowed()==ETrue Connection().State()==EActive

leave: KErrSIPInvalidTransactionState if canceling is not possible at all, or because the transaction is not in a proper state or the transaction is not related to a dialog.

leave: KErrSIPResourceNotAvailable if a required SIP Client API object has been deleted

capability: NetworkServices

Returns: SIP CANCEL transaction, ownership is transferred.

NewL ( RStringF, MTransactionAssociation &, CSIPRefresh * )

CSIPClientTransaction *	NewL	(	RStringF	aType,
			MTransactionAssociation &	aAssociation,
			CSIPRefresh *	aRefresh = 0
		)	[static]

Instantiates a CSIPClientTransaction object, leaves on failure.

Parameter	Description
aType	Identifies the transaction type
aAssociation	Object to which the transaction is associated with.
aRefresh	If transaction is refreshed, this points to a CSIPRefresh, otherwise this is NULL. Ownership is not transferred.

Returns: SIP client transaction, ownership is transferred.

NewLC ( RStringF, MTransactionAssociation &, CSIPRefresh * )

CSIPClientTransaction *	NewLC	(	RStringF	aType,
			MTransactionAssociation &	aAssociation,
			CSIPRefresh *	aRefresh = 0
		)	[static]

Instantiates a CSIPClientTransaction object and pushes it into CleanupStack, leaves on failure.

Parameter	Description
aType	Identifies the transaction type
aAssociation	Object to which the transaction is associated with.
aRefresh	If transaction is refreshed, this points to a CSIPRefresh, otherwise this is NULL. Ownership is not transferred.

Returns: SIP client transaction, ownership is transferred.

Refresh ( )

IMPORT_C const CSIPRefresh *

Refresh

(

)

const

Gets the associated refresh with the transaction. If the refresh is associated with the transaction, transaction will be refreshed at defined interval.

Returns: associated refresh or 0-pointer if there's no associated refresh. Ownership isn't transferred.

Refresh ( )

CSIPRefresh *

Refresh

(

)

Gets the associated refresh with the transaction and allows modification fo the refresh. This method is for internal use only.

Returns: associated refresh or 0-pointer if there's no associated refresh. Ownership isn't transferred.

RemoveRefresh ( )

void

RemoveRefresh

(

)

Clears the association from ClientTransaction to CSIPRefresh

ResponseElements ( )

IMPORT_C const CSIPResponseElements *

ResponseElements

(

)

const

Reimplemented from CSIPTransactionBase::ResponseElements()const

Gets response elements of the most recent response.

Returns: Response elements. Ownership isn't transferred.

SetRequestId ( TUint32 )

void

SetRequestId

(

TUint32

aRequestId

)

Sets the RequestId.

Pre-condition: iRequestId == 0
aRequestId != 0

Parameter	Description
aRequestId	RequestId obtained from SIP client
