Hello,
Hao Zong reported some missing Details in the JavaDoc of
ByteArrayOutputStream#write. While I dont think it is critical we should
probably fix it, since a user asked for it.
I am willing to go through the streams of [IO] and adjust them, but I Need to
know how:
a) Remove the JavaDoc of those overwritten API methods completely. This will
inherit the JavaDoc from the official Stream classes which is in this case
aproperiate and complete. This will make a good JavaDoc and shortst possible
Code but the Code Looks underdocumented then.
b) Like a) but Keep a non-Javadoc comment giving the existing short description
and a note to the effect of not having JavaDoc. This retains the full JavaDoc
doc, the source is however a bit longer with a uncommon block comment.
c) Use javadoc with @{inheritDoc}. This makes it clear what is going on,
however the @Throws documentation would Need to be replicated as it is not
inherited.
d) Expand the existing documentation. This will take most work and space in the
Code
Whats your Preference? I would really like to use a) in this case, is this
acceptable?
Gruss
Bernd

Bernd Eckenfels commented on IO-564:
------------------------------------
The functionality is defined in the `java.io.OutputStream`. It defines in the
description some of the runtime exceptions. I am not sure if we should
duplicate the description. Maybe inherit the doc?
> If off is negative, or len is negative, or off+len is greater than the length
> of the array b,
> then an IndexOutOfBoundsException is thrown.
Also when we copy the description, should we use @throws for IOOBE and NPE?
> 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.
