[jira] [Commented] (ARROW-6603) [C#] ArrayBuilder API to support
writing nulls
[ https://issues.apache.org/jira/browse/ARROW-6603?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16938975#comment-16938975 ]
Anthony Abate commented on ARROW-6603:
--------------------------------------
I have a few extension methods that do this - on thing i noticed, the spec seems to refer to terms NullBitmap and ValidityBitmaps - I think ValidityBitmap might be the more correct term since 1 = valid, whereas NullBitmap sounds like 1 = null. My first attempt at creating the nullbitmap inverted all the values
