QKnxNetIpSessionRequestProxy Class

The QKnxNetIpSessionRequestProxy class provides the means to introspect session request data inside the generic QKnxNetIpFrame class and to create a KNXnet/IP session request frame from provided data. 更多...

详细描述

This class is part of the Qt KNX module and currently available as a Technology Preview, and therefore the API and functionality provided by the class may be subject to change at any time without prior notice.

This frame will be sent by a KNXnet/IP secure client to the control endpoint of the KNXnet/IP secure server to initiate the secure session setup handshake for a new secure communication channel. The maximum time a KNXnet/IP secure client will wait for a response of the KNXnet/IP secure server is 10 seconds.

注意： When using QKnxNetIpSessionRequestProxy, 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 session request information:

auto netIpFrame = QKnxNetIpFrame::fromBytes(...);
const QKnxNetIpSessionRequestProxy proxy(netIpFrame);
if (!proxy.isValid())
    return;
auto endPoint = proxy.controlEndpoint();
auto publicKey = proxy.publicKey();

成员函数文档编制

QKnxNetIpSessionRequestProxy:: QKnxNetIpSessionRequestProxy (const QKnxNetIpFrame & frame )

Constructs a proxy object to read the session request information carried by the specified KNXnet/IP frame frame .

`[static]` QKnxNetIpSessionRequestProxy::Builder QKnxNetIpSessionRequestProxy:: builder ()

Returns a builder object to create a KNXnet/IP session request frame.

QKnxNetIpHpai QKnxNetIpSessionRequestProxy:: controlEndpoint () const

Returns the control endpoint from the generic KNXnet/IP session request frame.

bool QKnxNetIpSessionRequestProxy:: isValid () const

返回 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.

注意： KNXnet/IP session request frames currently have a fixed size of 46 字节。

QKnxByteArray QKnxNetIpSessionRequestProxy:: publicKey () const

Returns the public key from the generic KNXnet/IP session request frame. The public key needs to be generated using the Curve25519 algorithm and has a fixed size of 32 字节。
