The QKnxNetIpDisconnectResponseProxy class provides the means to read a KNXnet/IP disconnection response from the generic QKnxNetIpFrame class and to create a disconnection response frame based on the information.
A KNXnet/IP device terminates a data channel connection by sending a disconnection request to its communication partner's control endpoint. The KNXnet/IP device receiving the disconnection request acknowledges the operation with a KNXnet/IP disconnection response frame, which signals the final termination of a communication channel.
Note: When using QKnxNetIpDisconnectResponseProxy, care must be taken to ensure that the referenced KNXnet/IP frame outlives the proxy on all code paths, lest the proxy ends up referencing deleted data.
The following code sample illustrates how to read the disconnection response information sent by a KNXnet/IP client:
Member Function Documentation
QKnxNetIpDisconnectResponseProxy::QKnxNetIpDisconnectResponseProxy(const QKnxNetIpFrame &frame)
Constructs a proxy object to read the disconnection response information carried by the specified KNXnet/IP frame frame.
[static] QKnxNetIpDisconnectResponseProxy::Builder QKnxNetIpDisconnectResponseProxy::builder()
Returns a builder object to create a KNXnet/IP disconnection response frame.
quint8 QKnxNetIpDisconnectResponseProxy::channelId() const
Returns the ID of the communication channel between a KNXnet/IP client and server.
true if the frame contains initialized values and is in itself valid, otherwise returns
false. A valid KNXnet/IP frame consists of at least a valid header and a size in bytes corresponding to the total size of the KNXnet/IP frame header.
See also QKnxNetIpFrameHeader::totalSize().
Returns the status of the communication channel between a KNXnet/IP client and server.
