Detailed Description

template<class T>
class OFSetIterator< T >

This template class represents an iterator class for corresponding set data structures in ofstd.

Note the following properties of this class:

• even if the underlying set is unordered, it does have an internal order which can be used for iteration purposes
• a reference to the set which shall be iterated over will be remembered inside an object of OFSetIterator<T>; the set will NOT be copied
• it is possible to iterate from beginning to end or from end to beginning of the underlying set using Next() or Prev() (see below)
• if an element from the set is removed during the iteration, the iteration process has to be canceled and restarted
• two OFSetIterators can be compared through operators == and !=; two iterators are considered to be identical, if and only if they operate on the exact same set (identical memory addresses) and they currently refer to the same element

Constructor & Destructor Documentation

OFSetIterator()

template<class T>

OFSetIterator< T >::OFSetIterator ( OFSet< T > & ofsetv )

inline

Constructor.

The iterator will be set to the set's first element.

Parameters

ofsetv

Set to which the created object shall be an iterator.

References ofset, and pos.

Referenced by operator!=(), and operator==().

Member Function Documentation

Object()

template<class T>

T * OFSetIterator< T >::Object ( )

inline

Returns the current element.

Returns

Pointer to the current original element in the set.

operator!=()

template<class T>

OFBool OFSetIterator< T >::operator!= ( const OFSetIterator< T > & other ) const

inline

Determines if two iterators are not identical.

Parameters

other

Iterator which shall be compared with this.

Returns

OFTrue if iterators are not identical, OFFalse otherwise.

operator==()

template<class T>

OFBool OFSetIterator< T >::operator== ( const OFSetIterator< T > & other ) const

inline

Determines if two iterators are identical.

Parameters

other

Iterator which shall be compared with this.

Returns

OFTrue if iterators are identical, OFFalse otherwise.
