Destructor.

Member Function Documentation

AddTagConnectionListener ( MNfcTagConnectionListener & )

IMPORT_C TInt

AddTagConnectionListener

(

MNfcTagConnectionListener &

aListener

)

Adds a new MNfcTagConnectionListener object to receive notification, when specified tag has detected in the proximity of the device. Only one listener can be added at time. The MNfcTagConnectionListener 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.

AddTagSubscriptionL ( const CNfcTagSubscription & )

IMPORT_C void

AddTagSubscriptionL

(

const CNfcTagSubscription &

aSubscription

)

Adds new Tag subscription to the NFC server.

May Leave:

KErrAlreadyExists, if CNfcTagSubscription is already added to NFC server.

Parameters
aSubscription	A new subscription to be added.

DoCancel ( )

void

DoCancel

(

)

[protected, virtual]

Reimplemented from CActive::DoCancel()

NewL ( RNfcServer & )

IMPORT_C CNfcTagDiscovery *

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 CNfcTagDiscovery *

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.

RemoveTagConnectionListener ( )

IMPORT_C void

RemoveTagConnectionListener

(

)

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

RemoveTagSubscription ( )

IMPORT_C void

RemoveTagSubscription

(

)

Removes current Tag subscription from the NFC server.

RunL ( )

void

RunL

(

)

[protected, virtual]

Reimplemented from CActive::RunL()

TagSubscriptionL ( )

IMPORT_C CNfcTagSubscription *

TagSubscriptionL

(

)

Returns current Tag subscription from the NFC server.

Return Value: Pointer to NfcTagSubscription-object. May leave:KErrNotFound, if CNfcTagSubscription has not been added yet.
