Project Description

ReOBJ:

R(estricted) E(xtended) Objects. Simple, reasonable fast, restricted/extended python objects.

HTML Documentation

HTML documentation of the project is hosted at: ReOBJ-HTML documentation

Or Package Documentation

Main Info

ReOBJ contains different restricted/extended python objects.

  • ReDICTs: Simple, reasonable fast, restricted/extended python dictionary objects.
  • ReLISTs: Simple, reasonable fast, restricted/extended list objects.
  • ReTUPLEs: Simple, reasonable fast, restricted/extended tuple objects.
  • ReMATRIXs: Simple, reasonable fast, restricted/extended list-of-tuples objects.

All `ReBASE classes - subclasses`:

Warning

for all ReBASE classes disabled methods

  • any class.copy()

    • e.g.: xy = myrlist.copy()
  • any class.clear()

    • e.g.: myrlist.clear()
  • any __setattr__()

  • any __delattr__()

  • any __add__()

  • can be dumped with json: but will lose any extra data like: key_order (list) or/and any extra_data dict

  • can be pickled

  • additional methods:

    • set_extra_data(), update_extra_data(), replace_extra_data(): Sets/updates key/value to the additional dictionary: extra_data

    • copy_recursively(): recursively copy: Supports recursively intermediate ReDICT, ReLIST, ReTUPLE, dicts, lists and tuples (and their subclasses: depending on there implementation though)

      • this will also copy any ReDICT / ReLIST / ReTUPLE / ReMATRIX extra_data dict and any key_order (list) and any extra_key_order (list)
    • copy_recursively_to_python_native_types(): recursively copy: changing all ReOBJ to native python types.

      • RdictIO, RdictFO, RdictFO2: to python `OrderedDict obj keeping their order (see also argument: use_extra_key_order)

      • all other ReDICT: objects will be replaced by normal python dict objs

      • all ReLIST obj will be replaced by normal python list objs

      • all ReTUPLE obj will be replaced by normal python tuple objs

      • all ReMATRIX obj will be replaced by normal python list of tuple objs

        Warning

        ReMATRIX tuple items (rows) are not recursively copied so there should be no dict, list ect.. just basic types

      Supports recursively intermediate ReDICT, ReLIST, ReTUPLE, dicts, lists and tuples (and their subclasses: depending on there implementation though)

      Note

      any ReOBJ set: extra_data will be lost

    • topickle(): returns a new pickled dumps byte string from the obj

    • tojson(): returns a new json dumps string from the obj

    • tojson_keeporder(): returns a new json dumps string from the obj keeping the order of any RdictIO, RdictFO, RdictFO2

      • this uses first the: copy_recursively_to_python_native_types()

Warning

comparisons do not take into consideration any key_order (list) or extra_data dict

ReDICT

Overview Differences

  • Edict is similar to a normal python dict but has some additional (extended) features

  • Rdict and RdictIO: can add new items after creation/initialization

  • RdictF and RdictFO, RdictFO2: F(ix) can not add new items after creation/initialization

  • Rdict and RdictF: do not have any key_order (list) nor any extra_key_order (list)

  • RdictIO and RdictFO, RdictFO2: O(rder) do have a key_order (list) plus an extra_key_order (list)

    • RdictIO: I(nsertion) O(rder): keeps track of the order new keys where added

    • RdictFO, RdictFO2: F(ix) O(rder): keeps track of the order of the keys when it was created/initialized

    • all three have the extra_key_order (list):
      • this is a list which can be optionally set with a user defined key order (can also include just a subset of keys)
    • all three can be converted to OrderedDict: keeping their key_order or optionally the extra_key_order

      • example usage to print an ordered json using the method: tojson_keeporder()
      example_rdictordered = RdictFO([
         ('key1', 'value1'),
         ('key2', 'value2'),
         ('key3', RdictIO([
            ('inner_key1', 'innervalue1'),
            ('inner_key2', 'innervalue2'),
         ], False)),
      ], False)
      
      json_dumps = example_rdictordered.tojson_keeporder(indent=3)
      print(json_dumps)
      

      Output will be:

      {
         "key1": "value1",
         "key2": "value2",
         "key3": {
            "inner_key1": "innervalue1",
            "inner_key2": "innervalue2"
         }
      }
      
    • RdictFO vs. RdictFO2: RdictFO can change the values. RdictFO2 can after creation not change the values

ReLIST

  • Elist is similar to a normal python list but has some additional (extended) features
  • Rlist: can add new items after creation/initialization
  • RlistF: F(ix) can not add new items after creation/initialization

ReTUPLE

  • Etuple is similar to a normal python tuple but has some additional (extended) features

ReMATRIX

  • Lmatrix is a List-Of-Tuples with some additional (extended) features
  • LmatrixF: F(ix) can not add new items (tuple-rows) after creation/initialization
