QKnxNetIpManufacturerDibProxy Class

The QKnxNetIpManufacturerDibProxy class provides the means to read the manufacturer specific device information from the generic QKnxNetIpDib class and to create a KNXnet/IP manufacturer specific device information block (DIB) structure. More...

QKnxNetIpManufacturerDibProxy::Builder builder()

Detailed Description

Note: When using QKnxNetIpManufacturerDibProxy, care must be taken to ensure that the referenced KNXnet/IP DIB structure outlives the proxy on all code paths, lest the proxy ends up referencing deleted data.

Reading the manufacturer specific device information can be achieved like this:

auto dib = QKnxNetIpDib::fromBytes(...);

QKnxNetIpManufacturerDibProxy proxy(dib);
if (!proxy.isValid())
    return;

auto id = proxy.manufacturerId();
auto data = proxy.manufacturerData();

Member Function Documentation

QKnxNetIpManufacturerDibProxy::QKnxNetIpManufacturerDibProxy(const QKnxNetIpDib &dib)

Constructs a proxy object with the specified KNXnet/IP DIB structure dib to read a manufacturer specific device information block.

[static] QKnxNetIpManufacturerDibProxy::Builder QKnxNetIpManufacturerDibProxy::builder()

Returns a builder object to create a KNXnet/IP manufacturer DIB structure.

QKnxNetIp::DescriptionType QKnxNetIpManufacturerDibProxy::descriptionType() const

Returns the description type of this KNXnet/IP structure if the object that was passed during construction was valid; otherwise returns QKnx::NetIp::Unknown.

bool QKnxNetIpManufacturerDibProxy::isValid() const

Returns true if the KNXnet/IP structure to create the object is a valid KNXnet/IP DIB structure; otherwise returns false.

QKnxByteArray QKnxNetIpManufacturerDibProxy::manufacturerData() const

Returns the manufacturer data if the object that was passed during construction was valid; otherwise returns an empty byte array.

quint16 QKnxNetIpManufacturerDibProxy::manufacturerId() const

Returns the manufacturer ID of this KNXnet/IP structure if the object that was passed during construction was valid; otherwise returns 0.
