net.sourceforge.processdash.util.TimedInputStream

A filter that ensures some other input stream is closed properly. When an input stream is opened, it is sometimes very important that the stream be closed properly. (For example, if a FileInputStream is not closed properly, it may prevent other logic from writing to that file until the process terminates.) However, sometimes an object creates an input stream, then hands it to another object for processing. The stream creator cannot be certain that the client will close it properly. This class acts as a janitor: if the input stream is not closed within a certain period of time, this class will close the stream on behalf of the misbehaving client. If the client using a TimedInputStream does not finish its work within the allotted time, subsequent reads may throw an IOException. The implication is that the client needs to perform its work in a timely manner. The constructor for this class allows a time limit to be set.

    public InputStream getInputStream(String resourceName) throws IOException {
        if (!checkResourceName(resourceName))
            return null;


        File f = new File(directory, resourceName);
        return new TimedInputStream(new BufferedInputStream(
                new FileInputStream(f)));
    }

            // note: this strategy will only work if we KNOW that people have
            // performed a "backupCollection" call immediately before calling
            // this method.  If any time intervenes, a legacy dashboard could
            // run a backup, and our "mostRecentBackup" could become an
            // incremental backup instead of a full backup.
            return new TimedInputStream(new BufferedInputStream(
                    new FileInputStream(mostRecentBackup)));
        else
            throw new IOException("No backup made since restart");
    }

        return SvnFile.resources.getString("Report.Locally_Modified");
    }


    public InputStream getContents() throws IOException {
        helper.waitTillReady();
        return new TimedInputStream(new FileInputStream(file));
    }
