[jira] [Commented] (IO-883) ByteArraySeekableByteChannel should optionally expose a read-only channel

    [ https://issues.apache.org/jira/browse/IO-883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18052124#comment-18052124 ]

------------------------------------

Hello [~kwin] 

Then why not just cast the instance to {{ReadableByteChannel}} and pass that to the relevant code?

> In certain cases there should be no writes being performed through the SeekableByteChannel. Similar as for files it should be possible to wrap it as read-only and throw {{NonWritableChannelException}} for all operations trying to write to the wrapped array.
