剪贴画:如何获得实例的槽字典

Question

文档包含以下示例代码：

...
klass = env.find_class('MyClass')
instance = klass.new_instance('instance-name')
instance['One'] = 1
instance['Two'] = 2

有没有一个内置的功能，给我字典的插槽和他们的价值？就像.Slots()的pyclips方法。

就像这样：

def get_slot_dict(clips_instance):
    slot_dict = {}
    for s in clips_instance.instance_class.slots():
        slot_dict[s.name] = clips_instance[s.name]
    return slot_dict

Answer 1

从clipspy 0.3.0开始，您可以迭代对象元数据来构造数据结构。

implied_fact = env.assert_string("(implied-fact 1 2 3)")
list(implied_fact)

[1, 2, 3]

template_fact = env.assert_string("(template-fact (template-slot a-symbol))")

list(template_fact)
[('template-slot', 'a-symbol')]

dict(template_fact)
{'template-slot': 'a-symbol'}

klass = env.find_class('MY-CLASS')
instance = klass.new_instance('instance-name')
instance['One'] = 1
instance['Two'] = 2

dict(instance)
{'One': 1, 'Two': 2}
