Examples of java.io.RandomAccessFile.readByte()

java.io.RandomAccessFile.readByte()
Reads an 8-bit byte value from this stream. @return byte the next byte value from the source stream. @throws IOException If a problem occurs reading from this DataInputStream. @see DataOutput#writeByte(int)

                            byte [] zfieNameBytes = new byte[zfieNameBytesLen];
                            raf.read(zfieNameBytes);
                            String eName = new String(zfieNameBytes, "UTF-8");


                            // Read isDir
                            boolean eIsDir = raf.readByte() == (byte)0 ? false : true;


                            // Read offset of bytes in the real Jar/Zip file
                            int eOffset = raf.readInt();


                            // Read size of the file in the real Jar/Zip file
