Review Comment:
How about explaining the meaning of "resource"?
```suggestion
* <p>Compared to {@link #createFunction(String, Class)}, this method
allows registering a user
* defined function by only providing a full path class name and a list
of resources that contain the
* implementation of the function along with its dependencies. Users
don't need to initialize the
* function instance in advance. The resource file can be a local or
remote JAR file.
