[jira] [Commented] (PYLUCENE-41) JArray type issue

["Andi Vajda (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PYLUCENE-41?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16405374#comment-16405374 ] 

Andi Vajda commented on PYLUCENE-41:
------------------------------------

The bug is not with creating the JArray('double')([1.0, 2.0]) array. This works with both python 2 and 3.

What is not working in jcc on python 3 is setting this array into the other array you created:

    >>> a=JArray('object')(5)
    >>> a[0] = JArray('double')([1.0, 2.0])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: JArray<double>[1.0, 2.0]

Nor does casting it to Object work:

    >>> from java.lang import Object
    >>> JArray('double')([1.0, 2.0]).cast_(Object)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: <class 'Object'>

This all seems to work fine in python 2, however.

> Hi,
>  
> In JCC 3.0 release version and early(2.7) it is possible to make a double array by:
>  
> {{mask = JArray('object')(5)}}
> {{for i in range(5)}}
>  {{    mask[i] = JArray('double')([1.0, 2.0])}}
> It gives in the <=3.0 following type of 'mask'
> JArray<object>[<Object: [D@3967e60c>, <Object: [D@60d8c9b7>, ...
> for svn version it gives a 'TypeError: JArray<double>[1.0, 2.0]' in the assignment to mask[i]
>  
> Not sure this is a bug or a change of how to do things.
> Best Regards
