Hao Zhong commented on IO-564:
------------------------------
This could be helpful.
> The rules of ByteArrayOutputStream.write are not documented.
> ------------------------------------------------------------
>
> Key: IO-564
> URL: https://issues.apache.org/jira/browse/IO-564
> Project: Commons IO
> Issue Type: Improvement
> Components: Streams/Writers
> Affects Versions: 2.6
> Reporter: Hao Zhong
>
> When I call the ByteArrayOutputStream.write method, it returns exceptions.
> Its API document is not quite useful, since it does not define any rules.
> From the thrown exceptions, I cannot get any useful information either. Until
> I read the code, I understand its usage:
> {code}
> public void write(final byte[] b, final int off, final int len) {
> if ((off < 0)
> || (off > b.length)
> || (len < 0)
> || ((off + len) > b.length)
> || ((off + len) < 0)) {
> throw new IndexOutOfBoundsException();
> } else if (len == 0) {
> return;
> }
> ...
> }
> {\code}
> Would you please explicitly introduce the rules in the doucment? Or, would
> you please add more messages to the thrown exception? Both ways can make the
> API easier to understand.
