QNearFieldTagType2::QNearFieldTagType2 ( QObject * parent = 0 )

Constructs a new tag type 2 near field target with parent.

QNearFieldTagType2::~QNearFieldTagType2 ()

Destroys the tag type 2 near field target.

bool QNearFieldTagType2::handleResponse ( const QNearFieldTarget::RequestId & id, const QByteArray & response ) [virtual protected]

Reimplemented from QNearFieldTarget::handleResponse().

bool QNearFieldTagType2::hasNdefMessage () [virtual]

Reimplemented from QNearFieldTarget::hasNdefMessage().

int QNearFieldTagType2::memorySize ()

Returns the memory size in bytes of the tag.

RequestId QNearFieldTagType2::readBlock ( quint8 blockAddress ) [virtual]

Requests 16 bytes of data starting at blockAddress. Returns a request id which can be used to track the completion status of the request.

Once the request completes successfully the response can be retrieved from the requestResponse() function. The response of this request will be a QByteArray.

See also requestCompleted() and waitForRequestCompleted().

RequestId QNearFieldTagType2::readNdefMessages () [virtual]

Reimplemented from QNearFieldTarget::readNdefMessages().

RequestId QNearFieldTagType2::selectSector ( quint8 sector ) [virtual]

Selects the sector upon which subsequent readBlock() and writeBlock() operations will act.

Returns a request id which can be used to track the completion status of the request.

Once the request completes the response can be retrieved from the requestResponse() function. The response of this request will be a boolean value, true for success; otherwise false.

Note: this request has a passive acknowledgement mechanism. The operation is deemed successful if no response is received within 1ms. It will therefore take a minimum of 1 millisecond for the requestCompleted() signal to be emitted and calling waitForRequestCompleted() on the returned request id may cause the current thread to block for up to 1 millisecond.

Type QNearFieldTagType2::type () const [virtual]

Reimplemented from QNearFieldTarget::type().

quint8 QNearFieldTagType2::version ()

Returns the NFC Tag Type 2 specification version number that the tag supports.

bool QNearFieldTagType2::waitForRequestCompleted ( const RequestId & id, int msecs = 5000 ) [virtual]

Reimplemented from QNearFieldTarget::waitForRequestCompleted().

RequestId QNearFieldTagType2::writeBlock ( quint8 blockAddress, const QByteArray & data ) [virtual]

Writes 4 bytes of data to the block at blockAddress. Returns a request id which can be used to track the completion status of the request.

Once the request completes the response can be retrieved from the requestResponse() function. The response of this request will be a boolean value, true for success; otherwise false.

Returns true on success; otherwise returns false.

RequestId QNearFieldTagType2::writeNdefMessages ( const QList<QNdefMessage> & messages ) [virtual]

Reimplemented from QNearFieldTarget::writeNdefMessages().
