class CommonReducer(dict):
|
|
'''
|
|
Object based on 'dict' that implements the binary addition (obj1 + obj1) and
|
|
accumulation (obj += obj2). These operations pass through to the entries in
|
|
the commonReducer.
|
|
|
|
Instances of commonReducer are also callable, with the syntax:
|
|
cr(key, value)
|
|
this is equivalent to cr += {key: value}.
