Examples of java.util.zip.ZipInputStream.skip()

java.util.zip.ZipInputStream.skip()
Skips specified number of bytes in the current ZIP entry. @param n the number of bytes to skip @return the actual number of bytes skipped @exception ZipException if a ZIP file error has occurred @exception IOException if an I/O error has occurred @exception IllegalArgumentException if n < 0

                if (entry.getName().equals(entryName)) {
                    result = entry.getSize();
                    if (result == -1) {
                        result = 0;
                        while (true) {
                            long x = file.skip(16 * Constants.IO_BUFFER_SIZE);
                            if (x == 0) {
                                break;
                            }
                            result += x;
                        }
