[jira] [Commented] (ARROW-15227) [Python] Verify methods in Cython bindings for constness and default values

["Antoine Pitrou (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-15227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17467695#comment-17467695 ] 

Antoine Pitrou commented on ARROW-15227:
----------------------------------------

Basically, Cython is not a C or C++ compiler. It just translates its own language into C/C++ that another tool will compile. So the C/C++ declarations that you give to Cython are just to allow it emit the right C/C++ code, they don't need to match the actual C/C++ APIs exactly (which is actually convenient in cases where the exact declarations cannot be faithfully represented in Cython).

> Some methods in Cython bindings do not have the {{const}} attribute as in C++. We need to verify that they match C++ methods in terms of constness and default values.
