Detailed Description

CNdefDiscovery provides the mechanism to discover NDEF messages, which are read from the NFC tags.

Since: S60 ?S60_version

Member Function Documentation

AddNdefMessageListener ( MNdefMessageListener & )

IMPORT_C TInt

AddNdefMessageListener

(

MNdefMessageListener &

aListener

)

Adds a new MNdefMessageListener object to listen received NDEF-message actions. Only one listener can be added at the time. MNfcNdefListener must be added before calling any other method of this interface.

Parameters
aListener	Listener to be added.

Return Values

KErrAlreadyExists	If listener already exists.
KErrNone	If successful, otherwise one of the system-wide errcodes.

AddNdefSubscription ( const CNdefRecord::TNdefRecordTnf, const TDesC8 & )

IMPORT_C TInt	AddNdefSubscription	(	const CNdefRecord::TNdefRecordTnf	aTnf,
			const TDesC8 &	aType
		)

Adds NDEF-subscription to NFC server.

Parameters
aTnf	TNF of the message the application is interested in.
aType	Type of the message the application is interested in.

Return Values

KErrBadHandle	If MNdefMessageListener isn't added.
KErrNone	If successful, otherwise one of the system-wide errcodes.

DoCancel ( )

void

DoCancel

(

)

[protected, virtual]

Reimplemented from CActive::DoCancel()

NewL ( RNfcServer & )

IMPORT_C CNdefDiscovery *

NewL

(

RNfcServer &

aNfcServer

)

[static]

Creates a new instance of this class.

Parameters
aNfcServer	Reference to NFC server.

Return Value: Pointer to the newly created instance.

NewLC ( RNfcServer & )

IMPORT_C CNdefDiscovery *

NewLC

(

RNfcServer &

aNfcServer

)

[static]

Creates a new instance of this class.

Parameters
aNfcServer	Reference to NFC server.

Return Value: Pointer to the newly created instance.

RemoveAllNdefSubscription ( )

IMPORT_C void

RemoveAllNdefSubscription

(

)

Removes all NDEF subscription from the NFC server.

RemoveNdefMessageListener ( )

IMPORT_C void

RemoveNdefMessageListener

(

)

Removes MNdefMessageListener object. After calling this method, all actions related to this listener will be canceled.

RemoveNdefSubscription ( const CNdefRecord::TNdefRecordTnf, const TDesC8 & )

IMPORT_C void	RemoveNdefSubscription	(	const CNdefRecord::TNdefRecordTnf	aTnf,
			const TDesC8 &	aType
		)

Removes NDEF-subscription from the NFC server. If specified NDEF-subscription is not found, this method returns silently without any actions.

Parameters
aTnf	TNF of the message.
aType	Type of the message.

RunError ( TInt )

TInt

RunError

(

TInt

aError

)

[protected, virtual]

Reimplemented from CActive::RunError(TInt)

RunL ( )

SendNdefMessageL ( const CNdefMessage & )

IMPORT_C void

SendNdefMessageL

(

const CNdefMessage &

aMessage

)

Sends NDEF message to NFC server to handle it. If contain of given message is unknown for NFC server confirmation query with warning message will be launched.

Parameters
aMessage	Pointer to CNdefMessage, which will be handled in NFC server.
