Class IlcFloatExpIterator

An instance of the class IlcFloatExpIterator is an iterator that traverses the values belonging to the domain of a constrained discrete floating-point expression. A discrete floating-point variable is an instance of IlcFloatVar defined by this constructor:

IlcFloatVar

In other words, it is a floating-point variable with an enumerated domain.

An iterator of this class will not traverse the domain of a continuous floating-point variable (that is, one created by the other constructors of IlcFloatVar) because its domain is represented by an interval (not an enumerated set).

For more information, see the concept Iterator.

This constructor creates an iterator associated with exp to traverse the values belonging to the domain of exp. exp must be a discrete floating-point expression.

This member function returns IlcTrue if there is a current element and the iterator points to it. Otherwise, it returns IlcFalse.

To traverse the values belonging to the domain of a constrained discrete floating-point expression, use the following code:

 IlcFloat val;
 for (IlcFloatExpIterator iter(exp); iter.ok(); ++iter){
         val = *iter;
         // do something with val
 }

This operator returns the current element, the one to which the invoking iterator points.

This operator advances the iterator to point to the next value in the domain of the constrained discrete floating-point expression.
