annotate src/memory/persistent.py @ 1451:9b88b19b1ca8
plugins xep-0060, xep-0277: added methods to serialise getItems result (before bridge transmission):
serItemsData is used for normal callbacks, and serItemsDataD for callbacks which return deferred. These methods simplifly the code by making the re-use of getItems more easy.
