implementation that filters certain DSC events.
Constructor Summary | |
FilteringEventListener(DSCFilter filter)
Main constructor. |
Method Summary | |
void |
processEvent(DSCEvent event,
DSCParser parser)
Called for each DSC event. You can call methods on the DSC parser to skip comments, for example. But implementations need to be good citizens and take into account that multiple listeners can be active at the same time and that they might interfere with other listeners. When returning from the call, state information such as filters should be restored. |
