22/**
23 * This class wraps different representations of a message. In its current
24 * version is allows to specify binary data (as void*) with a size specifying
25 * the number of bytes of data or an message object that can be
26 * serialized if necessary. The main idea is, that simulation environments
27 * do not necessarily need to serialize messages.
28 *
29 * For performance reasons methods of this class are inlined where possible!
