Checking for '\n' and EOF in input

[Brett_Meyer]

Hello,

I have a custom loader function to read in a parsed schema from some log files, 
but it seems there is a problem with some of the log files and I need to detect 
if the end of a line in the log does not end with '\n' or is EOF when loading 
from the file.  I'm currently running Pig 0.8.0 with Hadoop 0.20.2, and I'm 
using the RecordReader class in my loader function to read in from a text file 
in the following way:

RecordReader in = null;

public Tuple getNext() throws IOException {
               try {
                              boolean notDone = in.nextKeyValue();
                              if (!notDone) {
                                             return null;
                              }
                              Text tval = (Text)in.getCurrentValue();
                              String val = tval.toString();

However, there's no way using this method to check for '\n' or EOF in the 
String val, so I'm not sure if it's possible to use another type of Record 
Reader or some other method to check for these values.  Any suggestions on how 
to do this in a custom Pig loader function?
