class CSIRO::Application::IndexBasedIterator< ContainerType, IsConst, ValueType, SizeType, DifferenceType, AccessorType >
Generally typedefs of this class will be declared inside the public section of the class definition. For example:
typedef Application::IndexBasedIterator<InputArray, InputScalar, true> const_iterator; typedef Application::IndexBasedIterator<InputArray, InputScalar, false> iterator;
Methods can then be defined to retrieve begin and end iterators:
iterator begin() { return iterator(*this, 0); } const_iterator begin() const { return const_iterator(*this, 0); } iterator end() { return iterator(*this, size()); } const_iterator end() const { return const_iterator(*this, size()); }
- Template Parameters
-
| ContainerType | The container type to iterate over |
| IsConst | Whether or not the iterator is a const_iterator type |
| ValueType | The type of the values to be returned when dereferencing the iterator. Becomes value_type. |
| SizeType | The size type of the container. Becomes size_type. |
| DifferenceType | The difference type of the container (for when iterators are subtracted). Becomes difference_type. |
| AccessorType | Callable access type for retrieving values from the container. Defaults to C::operator[]. |
