execution method of event handler

Processes the event. The method is called every time an event occurs, for which the event handler is responsible. Event handlers may declare themselves responsible for events by calling the corresponding SCIPcatch...() method. This method creates an event filter object to point to the given event handler and event data.

input:

  • scip : SCIP main data structure
  • eventhdlr : the event handler itself
  • event : event to process
  • eventdata : user data for the event
