Class IloNumExprArray

Definition file: ilconcert/iloexpression.h

The class IloNumExprArray.

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

Instances of IloNumExprArray 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.

Constructor Detail

IloNumExprArray

public IloNumExprArray(IloDefaultArrayI * i)

This constructor creates an empty array of numeric 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.

IloNumExprArray

public IloNumExprArray(const IloEnv env, IloInt n)

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

Method Detail

add

public void add(IloInt more, const IloNumExpr x)

This member function appends x to the invoking array. The parameter more indicates how many times.

add

public void add(const IloNumExpr x)

This member function appends x to the invoking array.

add

public void add(const IloNumExprArray array)

This member function appends the elements in array to the invoking array.

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.
