I'm wondering what techniques and/or library to use to implement the functionality of the linux command "tail -f ". I'm essentially looking for a drop in add-on/replacement for java.io.FileReader
. Client code could look something like this:
TailFileReader lft = new TailFileReader("application.log");
BufferedReader br = new BufferedReader(lft);
String line;
try {
while (true) {
line= br.readLine();
// do something interesting with line
}
} catch (IOException e) {
// barf
}
The missing piece is a reasonable implementation of TailFileReader
. It should be able to read parts of the file that exist before the file is opened as well as the lines that are added.
