类 PyFunction<R>

java.lang.Object

io.ray.api.function.PyFunction<R>

public class PyFunction<R>
extends Object

A class that represents a Python remote function.

 example_package/
 ├──__init__.py
 └──example_module.py

 in example_module.py there is a function.

 \@ray.remote
 def bar(v):
     return v

 then we can call the Python function bar:

 
 // bar returns input, so we have to set the returnType to int.class if bar accepts an int
 ObjectRef<Integer> res = actor.call(
    PyFunction.of("example_package.example_module", "bar", Integer.class),
    1);
 Integer value = res.get();

 // bar returns input, so we have to set the returnType to String.class if bar accepts a string
 ObjectRef<String> res = actor.call(
    PyFunction.of("example_package.example_module", "bar", String.class),
    "Hello world!");
 String value = res.get();
