Class IlcIntSetIterator

Definition file: ilcp/cpext.h

Include file: <ilcp/cpext.h>

The iterator class for sets of integers.

An instance of the class IlcIntSetIterator is an iterator that traverses the elements of finite sets of integers (instances of IlcIntSet).

For more information, see the concept Iterator.

Method Summary
`public`	`IlcIntSetIterator(IlcIntSet set)`
`public IlcBool`	`ok() const`
`public IlcInt`	`operator*() const`
`public IlcIntSetIterator &`	`operator++()`

public IlcIntSetIterator(IlcIntSet set)

This constructor creates an iterator associated with set to traverse its elements.

public IlcBool ok() const

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

To traverse the elements of a finite set integers, use the following code:

 IlcAny val;
 for(IlcIntSetIterator iter(set); iter.ok(); ++iter){
             val = *iter;
             // do something with val
 }

public IlcInt operator*() const

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

public IlcIntSetIterator & operator++()

This operator advances the iterator to point to the next value in the set.
