[sdo] [SDO-16]: What is the java.io.Serialization wire format ofDataGraphs?

[Radu Preotiuc-Pietro <radup@bea.com>]

Ron Barack:

The paragraph on the botton of pg 115 does not really help. First, it
requires that we know the length of the XMLDocument, and write that onto
the ObjectStream first. This more or less means that the XMLDocument
must be held in memory as a String or StringBuffer. This is not very
satisifying for large data graphs. Furthermare, don't we still need an
ExternalizableDelegator there, or are we simply supposed to push the XML
onto the ObjectStream?


Steve Brodsky:


Please clarify, this only seems to apply to calling
java.io.Serialization on DataGraph.
Clarified during the April 6 conf call that this issue refers only to
java.io.Serialization of the DataGraph.


Radu Preotiuc:

I wanted to cross-reference this to SDO-79, we need to clarify what the
role of DataGraph is, and then come up with details on its serialization
format.


Steve Brodsky:

Propose deferring to 3.0 unless there is a proposal to create the
equivalent of an ExternalizableDelegator for DataGraph.
