readLine()
is a low-level line-reading primitive. Most callers should
use readString('\n')
instead or use a Scanner.
readLine()
tries to return a single line, not including the end-of-line
bytes. If the line was too long for the buffer then more
is set and the
beginning of the line is returned. The rest of the line will be returned
from future calls. more
will be false when returning the last fragment
of the line. The returned buffer is only valid until the next call to
readLine()
.
The text returned from ReadLine does not include the line end ("\r\n" or "\n").
When the end of the underlying stream is reached, the final bytes in the
stream are returned. No indication or error is given if the input ends
without a final line end. When there are no more trailing bytes to read,
readLine()
returns null
.
Calling unreadByte()
after readLine()
will always unread the last byte
read (possibly a character belonging to the line end) even if that byte is
not part of the line returned by readLine()
.
