Detailed Description

Class that represents an iterator pointing to a contiguous interval \([a,b[\) as returned by IndexSet::begin_interval().

Definition at line 582 of file index_set.h.

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 666 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 1124 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 1138 of file index_set.h.

◆ IntervalIterator() [3/4]

IndexSet::IntervalIterator::IntervalIterator ( )
inline

Construct an empty iterator.

Definition at line 1132 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 1145 of file index_set.h.

◆ operator++() [2/2]

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

Postfix increment.

Definition at line 1154 of file index_set.h.

◆ operator*()

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

Dereferencing operator, returns an IntervalAccessor.

Definition at line 1164 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 1172 of file index_set.h.

◆ operator==()

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

Comparison.

Definition at line 1181 of file index_set.h.

◆ operator!=()

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

Inverse of ==.

Definition at line 1190 of file index_set.h.

◆ operator<()

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

Comparison operator.

Definition at line 1199 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 1208 of file index_set.h.

◆ accessor

IntervalAccessor IndexSet::IntervalIterator::accessor
