## Detailed Description

one datagram

This object represents one datagram of data sent or received through a datagram socket (as KDatagramSocket or derived classes). A datagram consists of data as well as a network address associated (whither to send the data or whence it came).

This is a lightweight class. Data is stored in a QByteArray, which means that it is explicitly shared.
