Re: [Py4j-users] question about target_ids for java objects

[Barthelemy D. <ba...@cs...>]

Hi,

JavaObject are not intended to be used directly, unless you want to 
extend Py4J in some ways.

The ids are provided by the Gateway on the java side and are available 
by calling Gateway.getBindings().

JavaObject instances are created when Java objects are accessed. e.g.,:

# in python
my_random = gateway.jvm.java.util.Random()

my_random is now a JavaObject instance and an id was generated for it.

Hope this helps,
Barthélémy
