Detailed Description

The first octet of the structure is the length of the structure and the second octet is an identifier that specifies the type of the structure.

If the structure's amount of data exceeds 252 octets, the first octet is 0xff and the next two octets contain the length as a 16 bit value. The fourth octet is then the identifier specifying the type of the structure.

Member Function Documentation

QKnxNetIpStructHeader::QKnxNetIpStructHeader(CodeType codeType, quint16 dataFieldSize)

Constructs a valid header object and sets the KNXnet/IP structure identifier to codeType and the data size to dataFieldSize and updates the header size and total size accordingly.

See also isValid(), code(), setCode(), dataSize(), and setDataSize().

QKnxNetIpStructHeader::QKnxNetIpStructHeader(CodeType codeType)

Constructs a valid header object and sets the KNXnet/IP structure identifier to codeType.

See also isValid(), code(), and setCode().

QKnxNetIpStructHeader::QKnxNetIpStructHeader()

Constructs an empty invalid header object.

See also isNull() and isValid().

QKnxNetIpStructHeader::~QKnxNetIpStructHeader()

Destroys the header object and releases all allocated resources.
