Data handling inside the PHP classes

Hi!

I improved the data handling inside the PHP classes. Each class normally has a list containing its child nodes. eg: AchAchievement has a list of AchTask nodes.

They are now organized in a doubly linked list. In addition to that an AVLtree is built to find nodes by their ID number. This allows later manipulation of the nodes and even reorganization. We need that for the admin tool, since changes to the structure will first be reflected within the actually loaded structure and the stored in the database.

Achievement Tracker (redone)

Hiho!

The achievement tracker has suffered some vital changes. We are now strictly event driven, which should give a nice performance boost.

XML data gets processed using SAX. This way we can avoid building a DOM tree inside the RAM while extracting data.

The parser knows two different types of data: values and entities. Values are simple values like "key=>value". Entities are dataset that belong together like "pet"=>(x,y,z,sheet_id,satiety,....)

Instead of asking the parser to extract information from the XML, the atom scripts now register which values or entities they are interested in, providing a callback method. Once all atoms have been registered, the parser is started. It will extract the data from top to bottom, sending it to the dispatcher which passes it on to the atoms. Worst case: no atom wants the data => nothing happens.

Well, that's ist basically :)
