Fields
• INITBUFSIZE
static final int INITBUFSIZE
• fInput
protected RandomAccessFile fInput
• fBuffer
protected byte[] fBuffer
• fOffset
protected int fOffset
• fEnd
protected int fEnd
Constructors
• RandomAccessFileWithByteLines
public RandomAccessFileWithByteLines(RandomAccessFile f)
Methods
• 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
