[jira] [Commented] (ARROW-14996) [Python][Gandiva] Deprecate or hide make_projector and make_filter testing utilities

["Will Jones (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-14996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17455909#comment-17455909 ] 

Will Jones commented on ARROW-14996:
------------------------------------

I thought these are an essential part of the API. The {{Filter}} and {{Projector}} classes both explicitly say to use these function to construct their respective objects.

> {{pyarrow.gandiva.{make_filter, make_projector}}} functions are only used from gandiva unittests. Additionally unexpected arguments can cause segmentations faults. We either should deprecate or hide these functions from the public API.
