Function Documentation

SCIP_RETCODE SCIPincludeObjPricer ( SCIP scip,
scip::ObjPricer objpricer,
SCIP_Bool  deleteobject 

creates the variable pricer for the given variable pricer object and includes it in SCIP

The method should be called in one of the following ways:

  1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyPricer* mypricer = new MyPricer(...); SCIP_CALL( SCIPincludeObjPricer(scip, &mypricer, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mypricer; // delete pricer AFTER SCIPfree() !
  1. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjPricer(scip, new MyPricer(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyPricer is called here
