dk.collections

Inversable dictionary.

class dk.collections.invdict.invdict

Inversable dict:

>>> -invdict({'key': 'val'}) == {'val': 'key'}

class dk.collections.mmap.mmap(**attrs)

Multi Map class, ie. a key/value collection where each key can occur multiple times. Implemented as a list of key/value tuples.

add(key, val)

append(kv)

Ordered Set. Items can only be added once, further additions have no effect. The iterator iterates over the items in insertion order.

class dk.collections.OrderedSet.oset(iterable=())

Ordered Set. Items can only be added once, further additions have no effect. The iterator iterates over the items in insertion order.

add(item)

Mapping classes.

class dk.collections.pset.defset(defval)

pset with default value.

class dk.collections.pset.pset(items=(), **attrs)

This code is placed in the Public Domain, or released under the wtfpl (http://sam.zoy.org/wtfpl/COPYING) wherever PD is problematic.

Property Set class. A property set is an object where values are attached to attributes, but can still be iterated over as key/value pairs. The order of assignment is maintained during iteration. Only one value allowed per key.

>>> x = pset()
>>> x.a = 42
>>> x.b = 'foo'
>>> x.a = 314
>>> x
pset(a=314, b='foo')

apply(fn)

Apply function fn to all values in self.

items()

keys()

pprint(indent=0, tab=' ', seen=None)

Pretty print the pset, indented.

remove(key)

Remove key from client vars.

values()

class dk.collections.pset.record(items=(), **attrs)

A property set with commit, rollback, and encoding translation.

changed()

Return list of fields that have changed since last commit.

commit()

Copy current state to self._history

decode(encoding)

Decode using encoding.

encode(encoding)

Encode using encoding.

fields

Verbose name of all fields.

rollback()

Copy snapshot from self._history into self.

strvals(empty='', none='NULL', encoding='u8')

Return a list of all values, formatted for human consumption.

trans(source='iso-8859-1', dest='utf-8')

Translate encoding.

class dk.collections.sdict.sdict(**attrs)

Sorted Dictionary class. Iterating over the sdict will give back the key/value pairs in order of insertion. A key can only be in a sdict once.
