Usage

Registration of the message handler for CRecordCliHandle:

addMessageHandler(CRecordCliHandle.ID,
                  this::asyncCliHandle);

Example implementation of the handler:

private boolean asyncCliHandle(@NotNull final CEnvelope aEnvelope,
                               @NotNull final CRecord aRecord) throws CException
{
    if (aEnvelope.isAnswer())
    {
        return false;
    }
    else
    {
        final String command = CRecordCliHandle.getCommand(aRecord,
                                                           "");
        if (QUIT.equals(command) || EXIT.equals(command))
        {
            final String[] args = CRecordCliHandle.getArguments(aRecord,
                                                                null);
            if (args != null && args.length >= 1 && args[0] != null)
            {
                int exitCode = CUtilInteger.fromObject(args[0],
                                                    0);
            }
            shutDown(exitCode);
        }
        aEnvelope.setResultSuccess();
        return true;
    }
}
