class IntervalIterator
 

Detailed Description

Dereferencing an IntervalIterator will return a reference to an object of this type. It allows access to a contiguous interval \([a,b[\) (also called a range) of the IndexSet being iterated over.

Definition at line 528 of file index_set.h.

Constructor & Destructor Documentation

◆ IntervalAccessor() [1/3]

IndexSet::IntervalAccessor::IntervalAccessor ( const IndexSet idxset,
const size_type  range_idx 
)
inline

Construct a valid accessor given an IndexSet and the index range_idx of the range to point to.

Definition at line 1027 of file index_set.h.

◆ IntervalAccessor() [2/3]

IndexSet::IntervalAccessor::IntervalAccessor ( const IndexSet idxset)
inlineexplicit

Construct an invalid accessor for the IndexSet.

Definition at line 1039 of file index_set.h.

◆ IntervalAccessor() [3/3]

IndexSet::IntervalAccessor::IntervalAccessor ( const IntervalAccessor other)
inlineprivate

Private copy constructor.

Definition at line 1046 of file index_set.h.

Member Function Documentation

◆ n_elements()

IndexSet::size_type IndexSet::IntervalAccessor::n_elements ( ) const
inline

Number of elements in this interval.

Definition at line 1058 of file index_set.h.

◆ is_valid()

bool IndexSet::IntervalAccessor::is_valid ( ) const
inline

If true, we are pointing at a valid interval in the IndexSet.

Definition at line 1067 of file index_set.h.

◆ begin()

IndexSet::ElementIterator IndexSet::IntervalAccessor::begin ( ) const
inline

Return an iterator pointing at the first index in this interval.

Definition at line 1075 of file index_set.h.

◆ end()

IndexSet::ElementIterator IndexSet::IntervalAccessor::end ( ) const
inline

Return an iterator pointing directly after the last index in this interval.

Definition at line 1084 of file index_set.h.

◆ last()

IndexSet::size_type IndexSet::IntervalAccessor::last ( ) const
inline

Return the index of the last index in this interval.

Definition at line 1098 of file index_set.h.

◆ operator=()

IndexSet::IntervalAccessor & IndexSet::IntervalAccessor::operator= ( const IntervalAccessor other)
inlineprivate

Private copy operator.

Definition at line 1108 of file index_set.h.

◆ operator==()

bool IndexSet::IntervalAccessor::operator== ( const IntervalAccessor other) const
inlineprivate

Test for equality, used by IntervalIterator.

◆ operator<()

bool IndexSet::IntervalAccessor::operator< ( const IntervalAccessor other) const
inlineprivate

Smaller-than operator, used by IntervalIterator.

Definition at line 1133 of file index_set.h.

◆ advance()

void IndexSet::IntervalAccessor::advance ( )
inlineprivate

Advance this accessor to point to the next interval in the index_set.

Definition at line 1144 of file index_set.h.
