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!

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:

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
