template <DimensionIndex InputRank = dynamic_rank,

          ContainerKind CKind = view>
class tensorstore::OutputIndexMapRange;

Represents a const range view of the output index maps for an index transform.

This range is valid only as long as the underlying index transform.

Types

using value_type = OutputIndexMapRef<InputRank>;
using reference = value_type;

Proxy reference to an output index map.

using iterator = OutputIndexMapIterator<InputRank>;

Iterator over output index maps.

using difference_type = DimensionIndex;

Iterator difference type.

Data members

constexpr const DimensionIndex extent = OutputRank;

The static extent of this range, equal to the static output rank of the transform.

Constructors

OutputIndexMapRange();

Constructs an invalid output index map range.

explicit OutputIndexMapRange(
    IndexTransform<InputRank, OutputRank, CKind> transform);

Constructs from an index transform.

OutputIndexMapRange(
    OutputIndexMapRange<OtherInputRank, OtherOutputRank, OtherCKind>
        other);

Converts from a compatible OutputIndexMapRange type.

Methods
