Java library for reading/searching huge text files.
cycleBackwards()
method seems to be reading 2 lines instead of reading a single line
For some reason, readPreviousLine()
is unable to obtain the first character in the first line, except for which everything seems to be working fine.
In the latest commit, cycleForward
works, but cycleBackward
is broken.
Current implementation uses a cursor position variable long bufferStartPointer
which contains the cursor location for the first line in buffer
,
initially, bufferStartPointer
is set as 0
when a cycleForward
operation is performed, bufferStartPointer
cannot be updated with the new cursor position since the only way to obtain it is to store cursor position for every line that is read.
readNextLine
removes any trailing newline characters, make readPreviousLine
also remove any trailing/preceding newline and/or carriage return characters, so that both are consistent.
use stringObj.replace("\n", "").replace("\r", "")
on the returned string
