Member Typedef Documentation

◆ 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.

Definition at line 860 of file index_set.h.

◆ value_type

using IndexSet::IntervalIterator::value_type = IntervalAccessor

Definition at line 861 of file index_set.h.

◆ difference_type

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

Definition at line 862 of file index_set.h.

◆ pointer

using IndexSet::IntervalIterator::pointer = IntervalAccessor *

Definition at line 863 of file index_set.h.

◆ reference

using IndexSet::IntervalIterator::reference = IntervalAccessor &

Definition at line 864 of file index_set.h.

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 1365 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 1379 of file index_set.h.

◆ IntervalIterator() [3/4]

IndexSet::IntervalIterator::IntervalIterator ( )
inline

Construct an empty iterator.

Definition at line 1373 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 1386 of file index_set.h.

◆ operator++() [2/2]

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

Postfix increment.

Definition at line 1395 of file index_set.h.

◆ operator*()

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

Dereferencing operator, returns an IntervalAccessor.

Definition at line 1405 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 1413 of file index_set.h.

◆ operator==()

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

Comparison.

Definition at line 1421 of file index_set.h.

◆ operator!=()

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

Inverse of ==.

Definition at line 1430 of file index_set.h.

◆ operator<()

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

Comparison operator.

Definition at line 1438 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 1448 of file index_set.h.
