Introduction to the class

Represents a rectangular area defined by its position (x, y) and dimensions (width, height).

The `NNRect` class provides methods to set and get the position and dimensions of the rectangle, as well as methods to retrieve the type of the rectangle and to generate a string representation of it. Additionally, it includes a method to clone the rectangle object, optionally performing a deep copy.

Introduction to the Class's Methods

  1. NNRect()

    • brief: Default constructor. Initializes the rectangle with default values (typically zero).

  2. NNRect(float x, float y, float width, float height)

    • brief: Parameterized constructor. Initializes the rectangle with the specified position and dimensions.

    • param

      • x: The x-coordinate of the top-left corner of the rectangle.

      • y: The y-coordinate of the top-left corner of the rectangle.

      • width: The width of the rectangle.

      • height: The height of the rectangle.

  3. void setX(uint32_t x)

    • brief: Sets the x-coordinate of the top-left corner of the rectangle.

    • param

      • x: The new x-coordinate.

  4. uint32_t getX()

    • brief: Gets the x-coordinate of the top-left corner of the rectangle.

    • return uint32_t: The x-coordinate of the top-left corner.

  5. void setY(uint32_t y)

    • brief: Sets the y-coordinate of the top-left corner of the rectangle.

    • param

      • y: The new y-coordinate.

  6. uint32_t getY()

    • brief: Gets the y-coordinate of the top-left corner of the rectangle.

    • return uint32_t: The y-coordinate of the top-left corner.

  7. void setWidth(uint32_t width)

    • brief: Sets the width of the rectangle.

    • param

      • width: The new width.

  8. uint32_t getWidth()

    • brief: Gets the width of the rectangle.

    • return uint32_t: The width of the rectangle.

  9. void setHeight(uint32_t height)

    • brief: Sets the height of the rectangle.

    • param

      • height: The new height.

  10. uint32_t getHeight()

    • brief: Gets the height of the rectangle.

    • return uint32_t: The height of the rectangle.

  11. std::string getType()

    • brief: Gets the type of the rectangle.

    • return string: A string representing the type of the rectangle.

  12. std::string toString()

    • brief: Generates a string representation of the rectangle. This method returns a string containing the position and dimensions of the rectangle.

    • return string: A string representation of the rectangle.

  13. std::shared_ptr<NNRect> clone(bool deep)

    • brief: Clones the rectangle object. This method creates a new `NNRect` object that is a copy of the current object. If `deep` is true, a deep copy is performed (although for this simple class, a shallow copy is sufficient since there are no pointers to dynamic memory).

    • param

      • deep: If true, perform a deep copy; otherwise, perform a shallow copy.

    • return shared_ptr<NNRect>: A shared pointer to the cloned rectangle object.
