The subject says it all basically. I have these data transfer services which use XML schemas. I have been using XMLBeans for a year or two with them. I have this one exchange using about 750MB or 1GB of RAM. I would like to be able to still use the provided interfaces for XMLBeans such as:
SomeTypeDocument doc = ... SomeNewElement e = doc.addSomeNewElement(); ... so = e.addSomeOtherNewElement(); The only way I could see this working would be if we could tell a single element to hold a partial object model so it existed as an object long enough to add more data/objects to it until it was finished then it would be flushed out to disk and when it was cleaned up its partial model would go away. Basically only so many objects and RAM would actually be used as needed and data would be flushed to disk. If there is anything in XMLBeans to make something like this happen please let me know. If it just isn't designed in then no worries. I would envision it working like: * Create a new document object which will be flushed instead of completely held in memory. Basically a full DOM could not exist for such a thing. * Add some top level element. * Tell that element to retain itself as more data will be added to it. * Other elements are added to it. They are set to not stay in memory or they are depending on whether they have other sub-elements. If not told to stick in the partial model their info is written to a buffer which is flushed when full. They are then just let go of when they are GCd. Basically any top level elements would flush their opening tag and attributes when any sub-elements are added or when a method was called to make it happen. Then they could flush their end element tags when any siblings are added or told to do so. Hopefully it would let me validate a file against an internal schema (as they are held in the XMLBeans created JAR files now) as well...without having to link to some external resource. So, just wondering if anything exists in XMLBeans to make this happen or if anyone knows of any other projects which do such a thing. Thanks in advance for any help or info, Wade --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
