Mixin implementing a Map.
This mixin has a basic implementation of all but five of the members of
Map.
A basic Map
class can be implemented by mixin in this class and
implementing keys
, operator[]
, operator[]=
, remove
and clear
.
The remaining operations are implemented in terms of these five.
The keys
iterable should have efficient length and contains
operations, and it should catch concurrent modifications of the keys
while iterating.
A more efficient implementation is usually possible by overriding some of the other members as well.
