QNdefMessage()
QNdefMessage(const int &records)

(since 6.2) QNdefMessage &operator=(const class QNdefMessage &other)

Detailed Description

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.

[constexpr noexcept] QNdefMessage::QNdefMessage()

Constructs a new empty NDEF message.

[explicit] QNdefMessage::QNdefMessage(const int &records)

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

[default] QNdefMessage::QNdefMessage(const class QNdefMessage &message)

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

[default, since 6.2] QNdefMessage &QNdefMessage::operator=(class QNdefMessage &&other)

This is an overloaded function.

Move assignment operator from QList<QNdefRecord>. Moves the other list of NDEF records to this NDEF record list.

After the operation, other will be empty.

This function was introduced in Qt 6.2.

[default, since 6.2] QNdefMessage &QNdefMessage::operator=(const class QNdefMessage &other)

This is an overloaded function.

Copy assignment operator from QList<QNdefRecord>. Assigns the other list of NDEF records to this NDEF record list.

After the operation, other and *this will be equal.

This function was introduced in Qt 6.2.
