readLine
public abstract int readLine(ByteArrayBuffer dst)
throws MaxLineLimitException,
IOException
- Reads one line of text into the given
ByteArrayBuffer
.
- Parameters:
dst
- Destination
- Returns:
- number of bytes copied or
-1
if the end of
the stream has been reached.
- Throws:
MaxLineLimitException
- if the line exceeds a limit on
the line length imposed by a subclass.
IOException
- in case of an I/O error.
unread
public abstract boolean unread(ByteArrayBuffer buf)
- Tries to unread the last read line.
Implementation may refuse to unread a new buffer until the previous
unread one has been competely consumed.
Implementations will directly use the byte array backed by buf, so
make sure to not alter it anymore once this method has been called.
