Usage

From source file:org.kalypso.commons.runtime.LogStatusWrapper.java

/**
 * @return an IStatus representation of this result.
 *///from w ww.  j av a  2  s .  c o  m
public IStatus toStatus() {
    if (!hasMessages())
        return Status.OK_STATUS;

    // the ErrorDialog cannot show a message which is too long: the dialog's
    // height would be bigger than the user's monitor. That's why we truncate
    // the summary string here. If the user wants to see more, he can have
    // a look at the log file using the 'details' button in the ErrorDialog
    final String truncatedSummary = StringUtils.left(m_summary, 512);
    // '\r' verschwinden lassen, da sonst der Status-Dialog zuviele Umbrche generiert
    final String msg = truncatedSummary.replace('\r', ' ') + "...\n" //$NON-NLS-1$
            + Messages.getString("org.kalypso.commons.runtime.LogStatusWrapper.5") //$NON-NLS-1$
            + m_logFile.toString();

    return new LogStatus(IStatus.WARNING, KalypsoCommonsPlugin.getID(), 0, msg, null, m_logFile, m_charsetName);
