Constructor & Destructor Documentation

◆ ConcatVectorIterator()

ConcatVectorIterator ( const PtrTVector *  curr,
pos,
const PtrTVector *  next 
)
inline
       @brief Constructor

       The iterator \b pos points into \b curr. When the iterator reaches
       the end of \b curr it then switches to the start of \b next.

       Given a pair of vectors \b curr and \b next, the start and end
       iterator for the concatenated sequence are given by
const ConcatVectorIterator<T> begin(curr, curr->begin(), next);
const ConcatVectorIterator<T> end(next, next->end(), 0);
       You can use ConcatVectorIterator for iterating through a single
       sequence by letting \b next be NULL.

Member Function Documentation

◆ operator!=()

bool operator!= ( const ConcatVectorIterator< T > &  other) const
inline

Tests whether the positions of two iterators are unequal.

Parameters
other[in] ConcatVectorIterator to compare with
Returns
true if unequal

◆ operator++() [1/2]

ConcatVectorIterator& operator++ ( )
inline

Increments the position of the iterator.

Returns
Reference to the incremented iterator

◆ operator++() [2/2]

ConcatVectorIterator operator++ ( int  )
inline

Increments the position of the iterator.

Returns
the ConcatVectorIterator with the value before the incrementation

◆ operator==()

bool operator== ( const ConcatVectorIterator< T > &  other) const
inline

Tests whether the positions of two iterators are equal.

Parameters
other[in] ConcatVectorIterator to compare with
Returns
true if equal
