yr.instance(*args, **kwargs) → InstanceCreator

Used to decorate classes that need to be remotely invoked on the openYuanRong system.

Parameters:

• class (class) – The class that needs to be remotely invoked.

• invoke_options (yr.InvokeOptions) – Invocation parameters.

Returns:

The creator of the decorated class. Data type is StatefulInstanceCreator.

Raises:

RuntimeError – If the object decorated by instance is not a class.

Example

Simple invocation example:

>>> import yr
>>> yr.init()
>>>
>>> @yr.instance
... class Instance:
...     sum = 0
...     def add(self, a):
...         self.sum += a
...     def get(self):
...         return self.sum
>>>
>>> ins = Instance.invoke()
>>> yr.get(ins.add.invoke(1))
>>> print(yr.get(ins.get.invoke()))
1
>>> ins.terminate()
>>>
>>> yr.finalize()

Function invocation example:

>>> import yr
>>> yr.init()
>>>
>>> @yr.instance
... class Instance:
...     def __init__(self):
...         self.sum = 0
...     def add(self, a):
...         self.sum += a
...     def get(self):
...         return self.sum

>>> @yr.instance
... class Instance2:
...    def __init__(self):
...        self.ins = Instance.invoke()
...    def add(self, a):
...        return self.ins.add.invoke(a)
...    def get(self):
...        return yr.get(self.ins.get.invoke())
>>>
>>> ins = Instance2.invoke()
>>> yr.get(ins.add.invoke(2))
>>> print(yr.get(ins.get.invoke()))
2
>>> ins.terminate()
>>>
>>> yr.finalize()
