Try it out, As long as all objects are cacheable it should work. For each
PdxWrapper you will see call in PdxSerailizer.

quite new to the PDX API, but I’m afraid it won’t work. Remember, my constraint
is to call one and only one method of PdxWriter for any field of my class. For
a nested collection I would have to call writeObjectArray at the root of the
object, but the inner PdxWrapper would itself dispatch to toData in
PdxSerializer. And that would mean other calls to PdxWriter. Am I missing
something? Thanks! Cosmin De : Hitesh Khamesra

Hi Cosmin: >>Are you maybe suggesting having a

Subject: RE: Serializing collections in PDX Hello Hitesh, Thanks, I think
that works fine for one-level deep collections of “Serializable”. However, I
don’t think that addresses nested collections. I thought I had that figured
out, but I still don’t see how, with just one call to a method from PdxWriter,
be able to write something like a std::vector<std::vector<int> >. Are you maybe
suggesting having a CacheableVector<CacheableVector<PdxWrapper> >? Meaning the
inner type is always wrapped in a PdxWrapper such that it is always a
“Serializable”? Thanks! Cosmin De : Hitesh

Objet : Re: Serializing collections in PDX Hi: You can CacheableVector
for this. And then pass this in following PdxWriter api.. virtual
PdxWriterPtr writeObject(const char* fieldName, CacheablePtr value) = 0; See
if this helps. Thanks. HItesh From: CREMARENCO Cosmin

Subject: Serializing collections in PDX Hello, Sorry for cross-posting,
this was also sent to dev (btw, the mailing list address for “user” doesn’t
appear on the homepage). I’m using PDX as a portable serialization format
between Java and C++. While in C++ I’m trying to serialize nested collections
(say std::vector<std::vector<std::string> > ). How can I do that with PDX? The
PdxWriter API says I’m only allowed flat arrays of types (and small number of
types at that). I can of course write recursively components of the collection,
but I’m forced to write “metadata” like the size of the collection and the
PdxWriter methods need a field name every time. These metadata fields will have
given names but will that not hinder indexing and the user view of the PDX
fields in the stream? What would you recommend in this case? Thanks! Cosmin
