Messages
The pykka.messages module contains Pykka’s own actor messages.
In general, you should not need to use any of these classes. However, they have been made part of the public API so that certain optimizations can be done without touching Pykka’s internals.
An example is to combine ask() and ProxyCall
to call a method on an actor without having to spend any resources on creating
a proxy object:
reply = actor_ref.ask(
ProxyCall(
attr_path=['my_method'],
args=['foo'],
kwargs={'bar': 'baz'}
)
)
Another example is to use tell() instead of
ask() for the proxy method call, and thus avoid the
creation of a future for the return value if you don’t need it.
It should be noted that these optimizations should only be necessary in very special circumstances.
New in version 2.0.
- class pykka.messages.ProxyCall(attr_path: AttrPath, args: Tuple[Any, ...], kwargs: Dict[str, Any])[source]
Message to ask the actor to call the method with the arguments.
- attr_path: AttrPath
List with the path from the actor to the method.
- args: Tuple[Any, ...]
List with positional arguments.
