Re: [Py4j-users] Converting Python collections to Java Collections

[Barthelemy D. <bar...@in...>]

Hi,

Thanks for using Py4j!

Py4J supports automated conversion to Java lists, sets, and maps, but
not array: http://py4j.sourceforge.net/advanced_topics.html#converting-python-collections-to-java-collections

You can still create an array from Py4J using gateway.new_array
(http://py4j.sourceforge.net/faq.html#how-to-create-an-array).

If you want Py4J to support automated conversion to Java arrays, you
can open an issue on github with an example of your use case.

There are a few challenges with automatically converting to Java
collections and to Java arrays in particular, but it might be possible
to create a converter for common cases.

Cheers,
Barthelemy
