[explicit] QRestAccessManager::QRestAccessManager(QNetworkAccessManager *manager, QObject *parent = nullptr)

Constructs a QRestAccessManager object and sets parent as the parent object, and manager as the underlying QNetworkAccessManager which is used for communication.

See also networkAccessManager().

[override virtual noexcept] QRestAccessManager::~QRestAccessManager()

Destroys the QRestAccessManager object.
