Hi,

I want to find some regular expressions in a file using java. I used
MappedByteBuffer in order to read the file (I do not want to read the
file line by line) but the problem is that I can not delete the file
after do the mapping between file and memory. Is there any way to
delete a file after do such a mapping? or read a file for regualr
expressions without using MappedByteBuffer? Thaks for your help.

I don't get it, why would you want to start reading a file and while at it,
delete it ?

Are you trying to do this? :
- read a file into memory
- delete the file (it was probably a temporary one)
- do a multiline regexp search/replace on it

If so, then I would use StringBuilder and FileReader (or buffered one) to get
every character in a String, close the file, delete it and then do the regexp.
