Lines Matching refs:ChainMap

27 :class:`ChainMap`       dict-like class for creating a single view of multiple mappings
42 :class:`ChainMap` objects
47 A :class:`ChainMap` class is provided for quickly linking a number of mappings
53 .. class:: ChainMap(*maps)
55     A :class:`ChainMap` groups multiple dicts or other mappings together to
65     A :class:`ChainMap` incorporates the underlying mappings by reference.  So, if
67     in :class:`ChainMap`.
82         Returns a new :class:`ChainMap` containing a new map followed by
86         is equivalent to: ``ChainMap({}, *d.maps)``.  This method is used for
95         Property returning a new :class:`ChainMap` containing all of the maps in
101         ``ChainMap(*d.maps[1:])``.
103     Note, the iteration order of a :class:`ChainMap()` is determined by
108         >>> list(ChainMap(adjustments, baseline))
131       :meth:`~collections.ChainMap.new_child` method and the
132       :attr:`~collections.ChainMap.parents` property.
