[Luis Rodriguez Gonzalez]

JSONiqfication for Archive Module Done.

Merge with trunk and resolved conflicts

[Chris Hillery (ceejatec)]

In archive_module.cpp:

1. Please don't leave commented-out code. Just delete it; it's in the version history if we ever need to refer back to it. For example, remove these lines:

+ //Item lNameItem = theFactory->createString(lName);
+ //lMemberName = theFactory->createString("name");

2. As discussed, if possible, create single zorba::Items for all the JSON object key strings, eg. "name", "size", etc. Possibly create those in the ArchiveModule constructor. Use those constants when creating JSON objects in EntriesIterator::next(), as well as comparing input values in ArchiveEntry::setValues() (and anywhere else it happens to be appropriate).

Also don't forget to assign a bug to yourself to create a JSON schema for this module, and to go back and update the module and test cases accordingly.

review: Needs Fixing

[Chris Hillery (ceejatec)]

Also, you have at least one </p> typo in archive.xq.

Always remember to run

  ctest -R moduleDocumentation

before committing, to be sure that your XQDoc is syntactically correct and that you didn't forget to document any parameters, etc.

Done.

You didn't actually create singleton zorba::Items for the JSON object key strings. Using C++ #defines isn't the same. This code will still create a separate zorba::Item for the string "name" for every single entry in every archive passed to a:entries().

I used #defines only for the strings that are into the Item, I tried to create static Items into ArchiveModule but at the end I got some linker errors at execution time, I did some research but couldn't fix it so I moved the Items to be created in EntriesIterator and OptionsIterator that in theory created only once insstead of creating one for each entry and options. I will upload a version with the Items created in ArchiveModule and if you have a chance pleaase take a look and let me know if you know how to fix it.

Testing global Items for Entries

56. By Chris Hillery on 2013-07-29

Definition of globalFormatName.

Changes to have global Items from ArchiveModule class made

[Chris Hillery (ceejatec)]

Global Items code looks good now!

As a general rule, don't put actual function definitions into header files. Certain small methods (accessors, usually) can be inline for efficiency, but anything more significant can cause code bloat and other problems. I moved the ArchiveModule() constructor definition into archive_module.cpp. With that done, everything looks fine.
