Class IloExprArray

Definition file: ilconcert/iloexpression.h

For each basic type, Concert Technology defines a corresponding array class. IloExprArray is the array class of the expressions class (IloExpr) for a model.

Instances of IloExprArray are extensible. That is, you can add more elements to such an array. References to an array change whenever an element is added to or removed from the array.

Most member functions in this class contain assert statements. For an explanation of the macro NDEBUG (a way to turn on or turn off these assert statements), see the concept Assert and NDEBUG.

IloExprArray

public IloExprArray(IloDefaultArrayI * i)

This constructor creates an empty array of expressions for use in a model. You cannot create instances of the undocumented class IloDefaultArrayI. As a parameter in this default constructor, it allows you to pass 0 (zero) as a value to an optional parameter in functions and member functions that accept an array as a parameter.

IloExprArray

public IloExprArray(const IloEnv env, IloInt n)

This constructor creates an array of n elements. Initially, the n elements are empty handles.

Method Detail

operator()

public IloNumExprArg operator()(IloNumExprArg anIntegerVariable)

This subscripting operator returns an expression argument for use in a constraint or expression. For clarity, let's call A the invoking array. When anIntegerVariable is bound to the value i, the domain of the expression is the domain of A[i]. More generally, the domain of the expression is the union of the domains of the expressions A[i] where the i are in the domain of anIntegerVariable.
