Method Detail

processEvent

void processEvent(DSCEvent event,
                  DSCParser parser)
           throws java.io.IOException,
                  DSCException

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.

Parameters:

event - the DSC event

parser - the DSC parser

Throws:

java.io.IOException - if an I/O error occurs

DSCException - if a DSC-specific error occurs
