Subject: Re: [jibx-users] Handling huge data (element)
Date: Wed, 08 Feb 2006 11:46:16 +1300
Hi Tony,
One way to handle this would be to write a custom serializer/deserializer
that converts to/from files. The deserializer would be called with the
large base64 data string, which it would write out to a file on the local
file system and then return the path to the file as the deserialized value
(or an actual File object, if you prefer). The serializer would be called
with the file path (or File object), and would return the text of the file.
This isn't completely ideal, in that you're still going to be working with
very large Strings for the base64 values, but you'd only need to have one
in memory at a time.

Hi to all,
I'm a newbie to Jibx, so please, forgive me if I post an already asked
question (enven if I don't find a post that could interest me in the
archive).
Here's my issue. I'd like to user Jibx to unmarshall/marshall a XML
document that could be huge (almost 100Mb, very rare but could be
happened).
The format of document is something like that :
<rootElement>
<childElement>
....
</childElement>
<Object>
<HugeData id="1" format="base64">data encoded in base64</HugeData>
<HugeData id="2" format="base64">data encoded in base64</HugeData>
</Object>
</rootElement>
In fact in the most of cases, I dont have to handle the <HugeData>.
Ive to extract them into a separated file only on demand. But when I
unmarshall the document I get a OutOfMemory exception (cause I bind it
with String type first). Then I try some others tips, but none works L.
I tried to write an empty marshaller (that implements IMarshaller,
IUnmarshaller, IAliasable, like the example with HashMapper) but I get the
same result L
So how could I do ? How Can I map the <HugeData> in order to avoid that
could be loaded in memory (Id like to write it directly into a file
instead) ? Does somebody manage to resolve this issue ?
Thanks in advance for your replies.
Cheers
Tony
