dip::Measurement::IteratorFeature::Iterator class

An iterator to visit all objects (rows) within a feature (column group) of the dip::Measurement table.

An object of this class can be treated (in only the most basic ways) as a std::array or std::vector.

Functions

auto begin() const -> dip::Measurement::ValueIterator: Iterator to the first value
auto data() const -> dip::Measurement::ValueType*: A pointer to the first value
auto end() const -> dip::Measurement::ValueIterator: Iterator one past the last value
auto FeatureName() const -> dip::String const&: Name of the feature
auto IsAtEnd() const -> bool: True if done iterating (do not call other methods if this is true!)
auto ObjectID() const -> dip::uint: ID of the object
auto ObjectIndex() const -> dip::uint: Index of the object (row number)
auto size() const -> dip::uint: Number of values

auto operator bool() const -> bool explicit: True if the iterator is valid and can be used
auto operator*() const -> dip::Measurement::ValueType&: Dereference to access the first value
auto operator++() -> dip::Measurement::IteratorFeature::Iterator&: Pre-increment, to access the next object
auto operator++(int ) -> dip::Measurement::IteratorFeature::Iterator: Post-increment, to access the next object
auto operator[](dip::uint index) const -> dip::Measurement::ValueType&: Index to access a specific value
