is a stream which allows writing the data of persistent objects.
Implementations of this service must fulfill the specifications of the DataOutputStream service; furthermore, the stream needs to be chained to a XMarkableStream. Therefore, it also provides the XMarkableStream 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:
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
interface com::sun::star::io::XActiveDataSource |
allows to set the underlying outputstream
interface com::sun::star::io::XConnectable |
allows to navigate via a chain of streams
interface com::sun::star::io::XObjectOutputStream |
allows to write the data to the stream.
