Examples of java.io.InputStream.reset()

java.io.InputStream.reset()
Reset this InputStream to the last marked location. If the readlimit has been passed or no mark has been set, throw IOException. This implementation throws IOException and concrete subclasses should provide proper implementations. @throws IOException If the stream is already closed or another IOException occurs.

                // use a buffered input stream to find out whether there actually
                // is a request body
                InputStream bin = new BufferedInputStream(in);
                bin.mark(1);
                boolean isEmpty = -1 == bin.read();
                bin.reset();
                if (!isEmpty) {
                    requestDocument = DomUtil.parseDocument(bin);
                }
            }
        } catch (IOException e) {
