operations_research::internal::UntypedGScipConstraintHandler Class Reference

Detailed Description

These classes implement a void pointer version of GScipConstraintHandler that performs a conversion to the more user-friendly templated implementation with ConstraintData. This parent class is needed as an untemplated version that SCIP_ConshdlrData can store.
