PyJack有一个函数replace_all_refs
可以替换内存中对象的所有引用。
文档中的一个示例:
>>> item = (100, 'one hundred')
>>> data = {item: True, 'itemdata': item}
>>>
>>> class Foobar(object):
... the_item = item
...
>>> def outer(datum):
... def inner():
... return ("Here is the datum:", datum,)
...
... return inner
...
>>> inner = outer(item)
>>>
>>> print item
(100, 'one hundred')
>>> print data
{'itemdata': (100, 'one hundred'), (100, 'one hundred'): True}
>>> print Foobar.the_item
(100, 'one hundred')
>>> print inner()
('Here is the datum:', (100, 'one hundred'))
调用 replace_all_refs
>>> new = (101, 'one hundred and one')
>>> org_item = pyjack.replace_all_refs(item, new)
>>>
>>> print item
(101, 'one hundred and one')
>>> print data
{'itemdata': (101, 'one hundred and one'), (101, 'one hundred and one'): True}
>>> print Foobar.the_item
(101, 'one hundred and one')
>>> print inner()
('Here is the datum:', (101, 'one hundred and one'))
