[jira] Commented: (IO-242) Pre- and post-processing support for ProxyReader/Writer

["Niall Pemberton (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12856966#action_12856966 ] 

Niall Pemberton commented on IO-242:
------------------------------------

The only comment I would make is that this proxy can now throw NPE if the String/char[]/CharBuffer is null - whereas in the past it would have just passed a null on to the delegate Reader/Writer.

I added test cases for nulls:

IMO at least for the ProxyWriter then it shouldn't now be throwing a NPE

> In IO-211 we added protected before/after methods for all read and write operations in ProxyInputStream and ProxyOutputStream. I now have a use case where I need similar functionality also for a Writer, so I've implemented the same feature also for ProxyReader and ProxyWriter. I'll attach the patch for review before committing it.
