I use the Scip solver from the Java api, via the Jni interface.

I want to implement an event handler (preferably in java), so that

  1. I can get some information about the progress of the solving, that I want to display

  2. Be able to interrupt the solving by calling SCIPinterruptSolve(SCIP *scip).

Event handlers are implemented in c and passed to scip via the following native method

SCIP_RETCODE SCIPincludeEventhdlrBasic  (   SCIP *  scip,
SCIP_EVENTHDLR **   eventhdlrptr,
const char *    name,
const char *    desc,
SCIP_DECL_EVENTEXEC((*eventexec))   ,
SCIP_EVENTHDLRDATA *    eventhdlrdata 
)

Can I implement an event handler in java?

How can I pass an event handler written in java to scip via the jni interface?

Note that there is no method corresponding to SCIPincludeEventhdlrBasic in the jni interface.

Unfortunately, this is not possible with the SCIP JNI interface since it does not support callbacks.
