iterator_category

using IndexSet::IntervalIterator::iterator_category = std::forward_iterator_tag

Mark the class as forward iterator and declare some alias which are standard for iterators and are used by algorithms to enquire about the specifics of the iterators they work on.

value_type

using IndexSet::IntervalIterator::value_type = IntervalAccessor

Definition at line 829 of file index_set.h.

difference_type

using IndexSet::IntervalIterator::difference_type = std::ptrdiff_t

pointer

using IndexSet::IntervalIterator::pointer = IntervalAccessor *

Constructor & Destructor Documentation

IntervalIterator() [1/4]

IndexSet::IntervalIterator::IntervalIterator ( const IndexSet *  idxset, const size_type  range_idx  )

inline

Construct a valid iterator pointing to the interval with index range_idx.

Definition at line 1333 of file index_set.h.

IntervalIterator() [2/4]

IndexSet::IntervalIterator::IntervalIterator ( const IndexSet *  idxset )

inlineexplicit

Construct an invalid iterator (used as end()).

Definition at line 1347 of file index_set.h.

IntervalIterator() [3/4]

IndexSet::IntervalIterator::IntervalIterator ( )

inline

Construct an empty iterator.

Definition at line 1341 of file index_set.h.

IntervalIterator() [4/4]

IndexSet::IntervalIterator::IntervalIterator ( const IntervalIterator &  other )

default

Copy constructor from other iterator.

Member Function Documentation

operator=()

IntervalIterator & IndexSet::IntervalIterator::operator= ( const IntervalIterator &  other )

default

Assignment of another iterator.

operator++() [1/2]

IndexSet::IntervalIterator & IndexSet::IntervalIterator::operator++ ( )

inline

Prefix increment.

Definition at line 1354 of file index_set.h.

operator++() [2/2]

IndexSet::IntervalIterator IndexSet::IntervalIterator::operator++ ( int  )

inline

Postfix increment.

Definition at line 1363 of file index_set.h.

operator*()

const IndexSet::IntervalAccessor & IndexSet::IntervalIterator::operator* ( ) const

inline

Dereferencing operator, returns an IntervalAccessor.

Definition at line 1373 of file index_set.h.

operator->()

const IndexSet::IntervalAccessor * IndexSet::IntervalIterator::operator-> ( ) const

inline

Dereferencing operator, returns a pointer to an IntervalAccessor.

Definition at line 1381 of file index_set.h.

operator==()

bool IndexSet::IntervalIterator::operator== ( const IntervalIterator &  other ) const

inline

Comparison.

Definition at line 1389 of file index_set.h.

operator!=()

bool IndexSet::IntervalIterator::operator!= ( const IntervalIterator &  other ) const

inline

Inverse of ==.

Definition at line 1398 of file index_set.h.

operator<()

bool IndexSet::IntervalIterator::operator< ( const IntervalIterator &  other ) const

inline

Comparison operator.

Definition at line 1406 of file index_set.h.

operator-()

int IndexSet::IntervalIterator::operator- ( const IntervalIterator &  p ) const

inline

Return the distance between the current iterator and the argument. The distance is given by how many times one has to apply operator++ to the current iterator to get the argument (for a positive return value), or operator-- (for a negative return value).

Definition at line 1416 of file index_set.h.

Member Data Documentation

accessor

IntervalAccessor IndexSet::IntervalIterator::accessor

private

Accessor that contains what IndexSet and interval we are pointing at.
