Niall Pemberton commented on IO-152:
------------------------------------
I understand the logical symmetry, but it still seems wrong that what is
essentially a "write" method method is named "read" rather than "write" and I
do think it fits in eactly with all the other "write" methods. On the
IOException point then we should make this clear in the javadocs
> Add ByteArrayOutputStream.readFrom(InputStream)

> 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.
