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
ofsetvSet 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.

References ofset, and pos.

◆ operator!=()

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

Determines if two iterators are not identical.

Parameters
otherIterator which shall be compared with this.
Returns
OFTrue if iterators are not identical, OFFalse otherwise.

References OFSetIterator().

◆ operator==()

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

Determines if two iterators are identical.

Parameters
otherIterator which shall be compared with this.
Returns
OFTrue if iterators are identical, OFFalse otherwise.
