<p>The buffered input stream implements <a class="el" href="classGio_1_1FilterInputStream.html" title="Filter Input Stream.">FilterInputStream</a> and provides for buffered reads. </p>
<p>By default, BufferedInputStream's buffer size is set at 4 kilobytes, but you can specify this to the constructor.</p>
<p>To get the size of a buffer within a buffered input stream, use <a class="el" href="classGio_1_1BufferedInputStream.html#a46384a96dc052e9d25e1a88281d69e40" title="Gets the size of the input buffer.">get_buffer_size()</a>.
