• INITBUFSIZE

   static final int INITBUFSIZE

• fInput

   protected RandomAccessFile fInput

• fBuffer

   protected byte[] fBuffer

• fOffset

   protected int fOffset

• fEnd

   protected int fEnd

• RandomAccessFileWithByteLines

   public RandomAccessFileWithByteLines(RandomAccessFile f) 

• readLine

   public boolean readLine(ByteBuf buf)  throws IOException

• eatNewline

   public boolean eatNewline()  throws IOException

Eat up one newline if present in the fBuffer. If a newline was eaten up return true otherwise false. This will handle mac (\r), unix (\n) and windows (\r\n) style of newlines transparently.

• getFilePointer

   public long getFilePointer()  throws IOException

• seek

   public void seek(long loc)  throws IOException

• fill

   protected boolean fill()  throws IOException

• fillForCapacity

   protected boolean fillForCapacity(int capacity)  throws IOException

Fill the fBuffer, keeping whatever is unread in the fBuffer and ensuring that "capacity" characters of total filled fBuffer space is available. Return false if the final amount of data in the fBuffer is less than capacity, otherwise return true.

• readFully

   public void readFully(byte[] arr, 
                         int off, 
                         int length)  throws IOException
