Detailed Description

An ordered list of data elements, formatted in memory for transmission over a socket or writing to a data file.

Data elements should be added one at a time, in order, to the Datagram. The nature and contents of the data elements are totally up to the user. When a Datagram has been transmitted and received, its data elements may be extracted using a DatagramIterator; it is up to the caller to know the correct type of each data element in order.

A Datagram is itself headerless; it is simply a collection of data elements.
