Function Documentation

◆ SCIPincludeObjConshdlr()

SCIP_RETCODE SCIPincludeObjConshdlr ( SCIP scip,
scip::ObjConshdlr objconshdlr,
SCIP_Bool  deleteobject 

creates the constraint handler for the given constraint handler 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) ); ... MyConshdlr* myconshdlr = new MyConshdlr(...); SCIP_CALL( SCIPincludeObjConshdlr(scip, &myconshdlr, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete myconshdlr; // delete conshdlr AFTER SCIPfree() !
  2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjConshdlr(scip, new MyConshdlr(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyConshdlr is called here

creates the constraint handler for the given constraint handler object and includes it in SCIP
