Jukka Zitting updated IO-152:
-----------------------------

    Attachment: IO-152.patch

Attached a patch with the proposed readFrom(InputStream) method and a simple test case.

I'll wait a few days for any objections before committing this.

> It would be useful to have a ByteArrayOutputStream.readFrom(InputStream) method to mirror the existing writeTo(OutputStream) method. A call like baos.readFrom(in) would be semantically the same as IOUtils.copy(in, baos), but would avoid an extra in-memory copy of the stream contents, as it could read bytes from the input stream directly into the internal ByteArrayOutputStream buffers.
