Class IloIntSet

An instance of this class offers a convenient way to represent a set of integer values as a constrained variable in Concert Technology.

An instance of this class represents a set of enumerated values. The same enumerated value will not appear more than once in a set. The elements of a set are not ordered. The class IloIntSet::Iterator offers you a way to traverse the elements of such a set.

If you are considering modeling issues where you want to represent repeated elements or where you want to exploit an indexed order among the elements, then you might want to look at the class IloAnyArray instead of this class for sets.

This constructor creates a set of integer values in the environment env from the elements in array. The optional flag withIndex corresponds to the activation or not of internal Hash Tables to improve speed of add/getIndex methods.

This constructor creates a set of numeric values in the environment env from the elements in array. The optional flag withIndex corresponds to the activation or not of internal Hash Tables to improve speed of add/getIndex methods.

This constructor creates an empty set (no elements) in the environment env. You must use the member function IloIntSet::add to fill this set with elements. The optional flag withIndex corresponds to the activation or not of internal Hash Tables to improve speed of add/getIndex methods.

This constructor creates a handle to a set of integer values from its implementation object.

This member function adds set to the invoking set. Here, "adds" means that the invoking set becomes the union of its former elements and the elements of set.

To calculate the arithmetic sum of values in an array, use the function IloSum.

This member function adds elt to the invoking set. Here, "adds" means that the invoking set becomes the union of its former elements and the new elt.

This member function returns a Boolean value (zero or one) that specifies whether set contains the invoking set. The value one specifies that the invoking set contains all the elements of set, and that the intersection of the invoking set with set is precisely set. The value zero specifies that the intersection of the invoking set and set is not precisely set.

This member function returns a Boolean value (zero or one) that specifies whether elt is an element of the invoking set. The value one specifies that the invoking set contains elt; the value zero specifies that the invoking set does not contain elt.

This member function removes the elements from the invoking set. In other words, the invoking set becomes the empty set.

Returns the first item of the collection.

This member function returns a pointer to the implementation object of the invoking set.

Returns the last item of the collection.

This method returns the value next to the given argument in the set.

If the given value does not exist, it throws an exception

If no value follows (that is, you are at the end of the set), it throws an exception.

See also getNextC, getPreviousC for circular search.

 S = {1,2,3,4}
 S.next(2,1) will return 3
 

This method returns the value next to the given argument in the set.

If the given value does not exist, it throws an exception.

If no value follows (that is, you are at the end of the set), it will give you the first value (circular search).

See also getNext, getPrevious.

This method returns the value previous to the given argument in the set.

If the given value does not exist, it throws an exception

If no value is previous (that is, you are at the beginning of the set), it throws an exception.

See also getNextC, getPreviousC for circular search.

This method returns the value previous to the given argument in the set.

If the given value does not exist, it throws an exception.

If no value is previous (that is, you are at the beginning of the set), it will give you the last value (circular search).

See also getNext, getPrevious.

This member function returns an integer specifying the size of the invoking set (that is, how many elements it contains).

This member function returns a Boolean value (zero or one) that specifies whether set intersects the invoking set. The value one specifies that the intersection of set and the invoking set is not empty (at least one element in common); the value zero specifies that the intersection of set and the invoking set is empty (no elements in common).

This member function removes all the elements of set from the invoking set.

This member function removes elt from the invoking set.

This member function changes the invoking set so that it includes only the elements of set. In other words, the invoking set becomes the intersection of its former elements with the elements of set.

This member function changes the invoking set so that it includes only the element specified by elt. In other words, the invoking set becomes the intersection of its former elements with elt.
