将IloNumArray打印到现有回调中的文件（C++）

Question

我试图使用fprintf()将IloNumArray打印到文件中。问题是我不知道Array的长度，因为它在现任回调中被getValues()方法填充。

在那里我遇到的问题回调的代码是以下之一：

ILOINCUMBENTCALLBACK3(MyFirstcallback, 
        IloCplex, cplex, 
        IloInt, contador, 
        IloNumVarArray, varenteras){ 
int i; 
int length=0; 
IloNum CurrentInc = MAX_COL; 
IloNum BestTime = 0; 
IloNum BestObj = MAX_COL; 
IloNumArray BestSol(varenteras.getEnv()); 

IloNum FirstTime = 0; 
IloNum FirstObj = MAX_COL; 
IloNumArray FirstSol(varenteras.getEnv()); 


if (hasIncumbent()) { 

    if (contador == 0 || contador == 1){ 
     contador+=1; 
     FirstObj=getIncumbentObjValue(); 
     getValues(FirstSol,varenteras); 
     FirstTime=cplex.getTime(); 


     length=sizeof(FirstSol)/sizeof(FirstSol[0]); 
//The first issue is here, length should be the size of the solution, and it's not giving it. 


     printf("El tiempo %lf el valor %lf el largo de la solucion %d \n",FirstTime,FirstObj,length);   
     FILE* out; 
     out = fopen("ResultadoPruebaTamanotest.txt","at+"); 
     fprintf(out,"%lf \t %lf \n",FirstTime,FirstObj); 
     for (i=0;i<length;i++){ 
      fprintf(out,"%d \t",FirstSol[i]); 
     } 
     fprintf(out,"\n"); 
    } 
} 

感谢您的帮助！

IloNumArray有一个getSize（）成员，它应该告诉你它有多少个元素。
