## Detailed Description

template<class T>
class OFOrderedSet< T >

This template class provides a data structure and operations for administrating an ordered set of elements of an arbitrary type.

Note the following properties of this class:

- an element which is inserted into the set will be copied
- the datatype of the set's elements has to support operator== so that it is possible to find a certain element
- it is allowed to insert identical elements into the set
- if a user requires to remove a certain element and if there are several elements which are identical to this element, only one element will be removed from the set
- when removing an element, the indices of the elements behind the removed element will be reduced by one
- the set will be ordered according to the point in time at which an element is inserted into the set; a new element will always be inserted at the end of the set

## ◆ Difference()

template<class T>

OFOrderedSet< T > OFOrderedSet< T >::Difference | ( | const OFOrderedSet< T > & | other | ) | const

Determines the difference this - other, i.e.

the set containing all the items found in this but not in other, and returns the resulting new set.

Parameters

  other | Second parameter for difference.

## ◆ Find()

template<class T>

virtual T * OFOrderedSet< T >::Find | ( | const T & | item | ) | const
| inline virtual

Tries to find a given object in the set.

In case the specified object could be found, a pointer to the corresponding element within the set is returned; in case the specified object could not be found, NULL will be returned.

Parameters

  item | Search pattern.

Returns
  Pointer to the corresponding element within the set or NULL.

Implements OFSet< T >.

## ◆ Insert() [1/2]

template<class T>

virtual void OFOrderedSet< T >::Insert | ( | const OFOrderedSet< T > & | other | ) |
| inline virtual

Inserts all items of another set into this set.

Parameters

  other | set whose items shall be inserted into the set.

References OFOrderedSet(), Insert(), OFSet< T >::items, and OFSet< T >::num.

## ◆ Insert() [2/2]

template<class T>

virtual void OFOrderedSet< T >::Insert | ( | const T & | item | ) |
| inline virtual

Inserts a new item into the set.

Parameters

  item | Item which shall be inserted into the set.

Implements OFSet< T >.

## ◆ InsertAt()

template<class T>

virtual void OFOrderedSet< T >::InsertAt | ( | const T & | item,
|  | unsigned int | idx )
| inline virtual

Inserts a new item at a certain position into the set.

Parameters

  item | Item which shall be inserted into the set.
  idx | Index of the position at which the item shall be inserted. The first position has index 0. Note that in case index is greater than the index of the last item, the new item will be inserted right behind the last item of the set.

## ◆ Intersection()

template<class T>

OFOrderedSet< T > OFOrderedSet< T >::Intersection | ( | const OFOrderedSet< T > & | other | ) | const

Determines the intersection of the two sets this and other, i.e.

the set containing all items which can be found in both this and other, and returns the resulting new set.

Parameters

  other | Second parameter for intersection.

Returns
  New set.
