We've implemented four iterator classes, namely ConstIterator, ConstReverseIterator, Iterator, and ReverseIterator, which provide essential functionality for iterating over the Vector class. These classes are located in the hgui::kernel namespace and are defined in the header file Iterator.hpp.

• ConstIterator
• ConstReverseIterator
• Iterator
• ReverseIterator

The ConstIterator class provides a const iterator for iterating over elements of a collection.

• T: Type of the elements in the collection.

• ConstIterator() noexcept: Default constructor.
• ConstIterator(const T* ptr) noexcept: Constructor with a pointer parameter.

• const reference operator*() const noexcept: Dereference operator.
• const pointer operator->() const noexcept: Arrow operator.
• const reference operator[](const difference_type offset) const noexcept: Subscript operator.
• ConstIterator<T>& operator++() noexcept: Pre-increment operator.
• ConstIterator<T> operator++(int) noexcept: Post-increment operator.
• ConstIterator<T>& operator--() noexcept: Pre-decrement operator.
• ConstIterator<T> operator--(int) noexcept: Post-decrement operator.

• ==, !=, <, <=, >, >=: Comparison operators for iterators.

#include <hgui/header/Iterator.h>

// Example Usage of ConstIterator
hgui::kernel::ConstIterator<int> it = /* initialize const iterator */;
for (; it != /* end const iterator */; it++) {
    // Process *it
}

Note: In the "Example Usage" section, make sure to replace /* initialize const iterator */ and /* end const iterator */ with actual code that initializes and specifies the end of your ConstIterator.

The ConstReverseIterator class provides a const reverse iterator for iterating over elements of a collection in reverse order.

• T: Type of the elements in the collection.

• ConstReverseIterator() noexcept: Default constructor.
• ConstReverseIterator(const T* ptr) noexcept: Constructor with a pointer parameter.

• const reference operator*() const noexcept: Dereference operator.
• const pointer operator->() const noexcept: Arrow operator.
• const reference operator[](const difference_type offset) const noexcept: Subscript operator.
• ConstReverseIterator& operator++() noexcept: Pre-increment operator.
• ConstReverseIterator operator++(int) noexcept: Post-increment operator.
• ConstReverseIterator& operator--() noexcept: Pre-decrement operator.
• ConstReverseIterator operator--(int) noexcept: Post-decrement operator.

• ==, !=, <, <=, >, >=: Comparison operators for iterators.

#include <hgui/header/Iterator.h>

// Example Usage of ConstReverseIterator
hgui::kernel::ConstReverseIterator<int> it = /* initialize reverse iterator */;
for (; it != /* end reverse iterator */; it++) {
    // Process *it
}

Note: In the "Example Usage" section, make sure to replace /* initialize reverse iterator */ and /* end reverse iterator */ with actual code that initializes and specifies the end of your ConstReverseIterator.

The Iterator class provides a non-const iterator for iterating over elements of a collection.

• T: Type of the elements in the collection.

• Iterator() noexcept: Default constructor.
• Iterator(T* ptr) noexcept: Constructor with a pointer parameter.

• reference operator*() const noexcept: Dereference operator.
• pointer operator->() const noexcept: Arrow operator.
• reference operator[](const difference_type offset) const noexcept: Subscript operator.
• Iterator& operator++() noexcept: Pre-increment operator.
• Iterator operator++(int) noexcept: Post-increment operator.
• Iterator& operator--() noexcept: Pre-decrement operator.
• Iterator operator--(int) noexcept: Post-decrement operator.

• ==, !=, <, <=, >, >=: Comparison operators for iterators.

#include <hgui/header/Iterator.h>

// Example Usage of Iterator
hgui::kernel::Iterator<int> it = /* initialize iterator */;
for (; it != /* end iterator */; it++) {
    // Process *it
}

Note: In the "Example Usage" section, make sure to replace /* initialize iterator */ and /* end iterator */ with actual code that initializes and specifies the end of your Iterator.

The ReverseIterator class provides a non-const reverse iterator for iterating over elements of a collection in reverse order.

• T: Type of the elements in the collection.

• ReverseIterator() noexcept: Default constructor.
• ReverseIterator(T* ptr) noexcept: Constructor with a pointer parameter.

• reference operator*() const noexcept: Dereference operator.
• pointer operator->() const noexcept: Arrow operator.
• reference operator[](const difference_type offset) const noexcept: Subscript operator.
• ReverseIterator& operator++() noexcept: Pre-increment operator.
• ReverseIterator operator++(int) noexcept: Post-increment operator.
• ReverseIterator& operator--() noexcept: Pre-decrement operator.
• ReverseIterator operator--(int) noexcept: Post-decrement operator.

• ==, !=, <, <=, >, >=: Comparison operators for iterators.

#include <hgui/header/Iterator.h>

// Example Usage of ReverseIterator
hgui::kernel::ReverseIterator<int> it = /* initialize reverse iterator */;
for (; it != /* end reverse iterator */; it++) {
    // Process *it
}

Note: In the "Example Usage" section, make sure to replace /* initialize reverse iterator */ and /* end reverse iterator */ with actual code that initializes and specifies the end of your ReverseIterator.
