[jira] [Commented] (ARROW-2063) [C++] Implement variant of FixedSizeBufferWriter that also supports reading (like MemoryMappedFile)

    [ https://issues.apache.org/jira/browse/ARROW-2063?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16552724#comment-16552724 ] 

Antoine Pitrou commented on ARROW-2063:
---------------------------------------

Instead of adding a whole new class for it, how about a new {{FixedSizeBufferWriter}} method that returns a {{BufferReader}} over the underlying buffer? Perhaps {{FixedSizeBufferWriter::GetReader}}.
