An instance refers to byte array that keeps packed data and passed to the instance thru either constructor or reset() method. Field Summary protected  byte[] buffer      protected  int offset      Constructor Summary public   BytePack(byte[] buffer)      Constructs an instance with given byte array. public   BytePack()      Constructs an instance. Method Summary public  void append(byte b)      Appends byte to packed data. public  void appendBytes(byte[] bytes)      Appends given bytes to packed data. public  void appendInt(int value)      Appends a 4-byte rpresentation of given integer value to packed data. public  byte extract()      Extracts next byte from packed data. public  byte[] extractBytes(int length)      Extracts next requested amount of bytes from packed data. public  int extractInt()      Extracts integer value previously stored by appendInt() from byte represnetation. public  byte[] release()      Removes internal reference to current byte array, returning the reference outside. public  void reset(byte[] buffer)      Resets state, setting packed data destination to given array and current offset to 0. public  void reset()      Resets state, setting current offset to 0. Field Detail buffer protected byte[] buffer(Code) Byte array that keeps packed data offset protected int offset(Code) Current offset in byte array Constructor Detail BytePack public BytePack(byte[] buffer)(Code) Constructs an instance with given byte array. Parameters:   buffer - byte array to either unpak data from or pack into. BytePack public BytePack()(Code) Constructs an instance. Method Detail append public void append(byte b)(Code) Appends byte to packed data. Parameters:   b - byte to append. appendBytes public void appendBytes(byte[] bytes)(Code) Appends given bytes to packed data. Parameters:   bytes - bytes to append. appendInt public void appendInt(int value)(Code) Appends a 4-byte rpresentation of given integer value to packed data. The value can be restored by extractInt() method. Parameters:   value - value to append extract public byte extract()(Code) Extracts next byte from packed data. byte extracted. extractBytes public byte[] extractBytes(int length)(Code) Extracts next requested amount of bytes from packed data. Parameters:   length - amount of bytes to extract (refernce to) newly created byte array that contains bytesextracted. extractInt public int extractInt()(Code) Extracts integer value previously stored by appendInt() from byte represnetation. value extracted release public byte[] release()(Code) Removes internal reference to current byte array, returning the reference outside. (reference to) byte array processed. reset public void reset(byte[] buffer)(Code) Resets state, setting packed data destination to given array and current offset to 0. Parameters:   buffer - new byte array to either unpak data from or pack into. reset public void reset()(Code) Resets state, setting current offset to 0.
