--------------------------------
Summary: Supply a hook method allowing Tailer actively determining
stop condition
Key: IO-345
URL: https://issues.apache.org/jira/browse/IO-345
Project: Commons IO
Issue Type: Improvement
Reporter: Martin Kresse
I am using the {{Tailer}} class on the server side and would like add some
timeout checking to automatically stop the tailer. With the current version, if
I want to avoid the usage of another thread, I can perform this check only
inside the methods of the {{TailerListener}}. If no events are generated (due
to the tailed file not changing), this check would never be executed.
Therefore I suggest the addition of a protected method, something like:
{code:title=Tailer.java|borderStyle=none}
protected boolean shouldRun() {
return this.run;
}
{code}
Instead of testing the boolean variable {{run}}, the {{Tailer}} thread would
call this method.
This would allow subclassing {{Tailer}} for adding some logic, which
dynamically decides whether the tailer should continue running or not. For
users not needing this feature, nothing would change.
