Detailed Description

The QNdefMessage class provides an NFC NDEF message.

A QNdefMessage is a collection of 0 or more QNdefRecords. QNdefMessage inherits from QList<QNdefRecord> and therefore the standard QList functions can be used to manipulate the NDEF records in the message.

NDEF messages can be parsed from a byte array conforming to the NFC Data Exchange Format technical specification by using the fromByteArray() static function. Conversely QNdefMessages can be converted into a byte array with the toByteArray() function.

Member Function Documentation

QNdefMessage::QNdefMessage ()

Constructs a new empty NDEF message.

QNdefMessage::QNdefMessage ( const QNdefRecord & record )

Constructs a new NDEF message containing a single record record.

QNdefMessage::QNdefMessage ( const QNdefMessage & message )

Constructs a new NDEF message that is a copy of message.

QNdefMessage::QNdefMessage ( const QList<QNdefRecord> & records )

Constructs a new NDEF message that contains all of the records in records.

QNdefMessage QNdefMessage::fromByteArray ( const QByteArray & message ) `[static]`

Returns an NDEF message parsed from the contents of message.

The message parameter is interpreted as the raw message format defined in the NFC Data Exchange Format technical specification.

If a parse error occurs an empty NDEF message is returned.

QByteArray QNdefMessage::toByteArray () const

Returns the NDEF message as a byte array.

The return value of this function conforms to the format defined in the NFC Data Exchange Format technical specification.

bool QNdefMessage::operator== ( const QNdefMessage & other ) const

Returns true if this NDEF message is equivalent to other; otherwise returns false.

An empty message (i.e. isEmpty() returns true) is equivalent to a NDEF message containing a single record of type QNdefRecord::Empty.
