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 indeces 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

Constructor & Destructor Documentation

template<class T >

OFOrderedSet< T >::OFOrderedSet ( const OFOrderedSet< T > & src ) [inline]

Copy constructor.

Parameters:

src	Source object of which this will be a copy.

Member Function Documentation

template<class T >

virtual OFBool OFOrderedSet< T >::Contains ( const T & item ) const [inline, virtual]

Determines if a certain item is contained in the set.

Parameters:

item	- Item which shall be looked for.

Returns:: OFTrue, if item is contained in the set, OFFalse otherwise.

Implements OFSet< T >.

template<class T >

OFOrderedSet<T> OFOrderedSet< T >::Difference ( const OFOrderedSet< T > & other ) const [inline]

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.

Returns:: New set.

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 >.

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 >.

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.

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.

template<class T >

OFOrderedSet<T> OFOrderedSet< T >::Intersection ( const OFOrderedSet< T > & other ) const [inline]

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.

template<class T >

virtual OFBool OFOrderedSet< T >::IsSubsetOf ( const OFOrderedSet< T > & other ) const [inline, virtual]

Determines if this is an actual subset of other, i.e.

if this is completely contained in other and other furthermore has additional elements.

Parameters:

other - Set which shall be compared with this.

Returns:: OFTrue if this is a subset of other, OFFalse otherwise.

template<class T >

virtual OFBool OFOrderedSet< T >::IsSupersetOf ( const OFOrderedSet< T > & other ) const [inline, virtual]

Determines if this is an actual superset of other, i.e.

if this completely contains other and furthermore has additional elements.

Parameters:

other - Set which shall be compared with this.

Returns:: OFTrue if this is a superset of other, OFFalse otherwise.

template<class T >

virtual OFBool OFOrderedSet< T >::operator!= ( const OFOrderedSet< T > & other ) const [inline, virtual]

Determines if two sets are not identical.

Parameters:

other Set which shall be compared with this.

Returns:: OFTrue if sets are not identical, OFFalse otherwise.

template<class T >

const OFOrderedSet<T>& OFOrderedSet< T >::operator= ( const OFOrderedSet< T > & src ) [inline]

operator=.

Parameters:

src	Source object whose values will be assigned to this.

Returns:: Reference to this.

template<class T >

virtual OFBool OFOrderedSet< T >::operator== ( const OFOrderedSet< T > & other ) const [inline, virtual]

Determines if two sets are identical.

Note that for ordered sets not only their elements have to be identical, but also the order of their elements has to be identical.

Parameters:

other Set which shall be compared with this.

Returns:: OFTrue if sets are identical, OFFalse otherwise.

template<class T >

virtual void OFOrderedSet< T >::Remove ( const T & item ) [inline, virtual]

Removes one item from the set.

Parameters:

item	Item which shall be inserted into the set.

Implements OFSet< T >.

template<class T >

virtual void OFOrderedSet< T >::RemoveByIndex ( unsigned int idx ) [inline, virtual]

Removes one item from the set.

Parameters:

idx	Index of the item which shall be removed from the set.

Implements OFSet< T >.

template<class T >

OFOrderedSet<T> OFOrderedSet< T >::SymmetricDifference ( const OFOrderedSet< T > & other ) const [inline]

Determines the symmetric difference of this and other, i.e.

the set containing all the items which can be found either in this or in other but not in the intersection of this and other, and returns the resulting new set.

Parameters:

other Second parameter for symmetric difference.

Returns:: New set.

template<class T >

OFOrderedSet<T> OFOrderedSet< T >::Union ( const OFOrderedSet< T > & other ) const [inline]

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

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

Parameters:

other Second parameter for union.

Returns:: New set.
