/** is a stream which allows writing the data of persistent objects.
<p>Implementations of this service must fulfill the specifications of the
<type>DataOutputStream</type> service; futhermore, the stream needs to be chained to a
<type>XMarkableStream</type>. Therefore, it also provides the <type>XMarkableStream</type>
interface, but it delegates the calls to the chained object.
The written objects are held until this instance is destroyed.
The references to the objects are written as four-byte integers
and begin at 1. Data format is written: </p>
<pre>
short InfoLength
long ObjectReference // 0 indicates no object
UTF ServiceName // length of 0 indicates this is only a reference
long ObjectLength // 0 if it is a reference or no object, otherwise the len of the object data
Object ObjectData // the data of the object
