Added an additional map to store all parts and be able to access them if needed.
Added public preconditions
Added private asserts
Excluded public overridden methods, since behaviour can be unexpected
Many exceptions got an improvement due to changed class or description or details it is providing.
Is not complete, needs to be done in patches in the regions, where it is needed, since some are just
swallowed.
Removed total usage of pure RuntimeExceptions to 0.
Deprecates the old usage of the AEItemDefinitions via the direct method access of
* blocks()
* parts()
* items()
* materials()
and thus use the new re-direct via definitions().
All definitions are now initialized, no matter what. But SubItems, Items and Blocks are not registered, if by chance are disabled.
Replaced String concat in loops with StringBuilder (performance)
Replaced for with keySet + Map.get() through for with entrySet (perf)
Changed inner classes to static classes, mostly struct like (memory)
