<DT>public interface <B>SharedInputStream</B></DL>
<P>
An InputStream that is backed by data that can be shared by multiple
readers may implement this interface. This allows users of such an
InputStream to determine the current positionin the InputStream, and
to create new InputStreams representing a subset of the data in the
original InputStream. The new InputStream will access the same
underlying data as the original, without copying the data.
