193 * Basic support for object serialization.
194 *
195 * Objects that support serialization should derive from this
196 * class. Such objects can largely be divided into two categories: 1)
197 * True SimObjects (deriving from SimObject), and 2) child objects
198 * (non-SimObjects).
199 *
200 * SimObjects are serialized automatically into their own sections
201 * automatically by the SimObject base class (see
202 * SimObject::serializeAll().
203 *
204 * SimObjects can contain other serializable objects that are not
205 * SimObjects. Much like normal serialized members are not serialized
206 * automatically, these objects will not be serialized automatically
207 * and it is expected that the objects owning such serializable
208 * objects call the required serialization/unserialization methods on
209 * child objects. The preferred method to serialize a child object is
210 * to call serializeSection() on the child, which serializes the
211 * object into a new subsection in the current section. Another option
212 * is to call serialize() directly, which serializes the object into
213 * the current section. The latter is not recommended as it can lead
214 * to naming clashes between objects.
215 *
216 * @note Many objects that support serialization need to be put in a
217 * consistent state when serialization takes place. We refer to the
218 * action of forcing an object into a consistent state as
219 * 'draining'. Objects that need draining inherit from Drainable. See
220 * Drainable for more information.
