Method Summary
public virtual voidinvoke(int issueid, char const * message)
Method Detail

invoke

public virtual void invoke(int issueid, char const * message)

Invoked by the modeling assistance callback.

If an object is registered with CPLEX by means of the method IloCplex::use(IloModelingAssistance::Callback*), then CPLEX will invoke this function of the registered object for each modeling assistance warning. These warnings will not be displayed in the engine log as they are by default when no callback is registered. For values of issueid, see the constants in the IloModelingAssistance namespace.

Note

Note: CPLEX will only invoke this function if the CPLEX parameter IloCplex::Param::Read::DataCheck is set to IloCplex::DataCheck::Assist. In addition, the parameter IloCplex::Param::Read::WarningLimit controls the number of times each type of modeling assistance warning will be reported (the rest will be ignored). See CPX_PARAM_DATACHECK and CPX_PARAM_WARNLIM in the Parameters of CPLEX Reference Manual.

Parameters:

issueid
The modeling assistance issue ID.
message
The modeling assistance warning string.
