Re: [Py4j-users] How to test if two objects are the same?

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

Hi,

enumerations are supported in py4j like regular classes.

Assuming the following Enum:

package py4j;

public enum MyEnum {
    Mon,
    Tue,
    Wed,
    Thu,
    Fri,
    Sat,
    Sun;
}


Here is some working code:
In [1]: from py4j.java_gateway import JavaGateway

In [2]: gateway = JavaGateway()

In [3]: my_enum = gateway.jvm.py4j.MyEnum

In [4]: my_enum.Sat
Out[4]: JavaObject id=o0

In [5]: my_enum.Sat == my_enum.Sat
Out[5]: True

In [6]: my_enum.Sat == my_enum.Sun
Out[6]: False

In [7]: sat = my_enum.Sat

In [8]: sat == my_enum.Sat
Out[8]: True

In [9]: sat == my_enum.Sun
Out[9]: False

Does that make sense?
