| SCIP_DECL_EVENTINITSOL | ( | EventhdlrNewSol::scip_initsol | ) |
solving process initialization method of event handler (called when branch and bound process is about to begin)
This method is called when the presolving was finished and the branch and bound process is about to begin. The event handler may use this call to initialize its branch and bound specific data.

| SCIP_DECL_EVENTEXITSOL | ( | EventhdlrNewSol::scip_exitsol | ) |
solving process deinitialization method of event handler (called before branch and bound process data is freed)
This method is called before the branch and bound process is freed. The event handler should use this call to clean up its branch and bound data.

| SCIP_DECL_EVENTDELETE | ( | EventhdlrNewSol::scip_delete | ) |
frees specific constraint data

| SCIP_DECL_EVENTEXEC | ( | EventhdlrNewSol::scip_exec | ) |
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 resposible 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.
