Class: Dimension

The Dimension class represents a 2D dimension or size, with utility functions for operations like area calculation and comparisons.

The source file for this class is located in os/framework/Dimension.h

Constructors​

Default Constructor​

Dimension();

Initializes the dimension to (0, 0).

From x and y​

Dimension(int16_t x, int16_t y);

Constructs a dimension from individual x and y values.

Parameters:

  • x (int16_t): The width.
  • y (int16_t): The height.

From Raw 32-bit Value​

Dimension(uint32_t rawByte);

Constructs a dimension from a 32-bit raw value.

Parameters:

  • rawByte (uint32_t): The raw data encoding x and y. The high 16 bits represent x, and the low 16 bits represent y.

Member Functions​

Contains​

bool Contains(Point point);

Checks if a point is within the dimension.

Parameters:

  • point (Point): The point to check.

Returns:

  • bool: true if the point is within the dimension, otherwise false.

Area​

uint32_t Area();

Calculates the area of the dimension.

Returns:

  • uint32_t: The area, calculated as x * y.

Operators​

Addition​

Dimension operator+(const Dimension& cp) const;

Adds two dimensions together.

Parameters:

  • cp (const Dimension&): The other dimension to add.

Returns:

  • Dimension: A new dimension resulting from the addition.

Inequality Comparison​

bool operator!=(const Dimension& cp) const;

Checks if two dimensions are not equal.

Parameters:

  • cp (const Dimension&): The other dimension to compare.

Returns:

  • bool: true if the dimensions are not equal, otherwise false.

Less Than Comparison​

bool operator<(const Dimension& cp) const;

Compares two dimensions. First compares x, and if they are equal, compares y.

Parameters:

  • cp (const Dimension&): The other dimension to compare.

Returns:

  • bool: true if the current dimension is smaller, otherwise false.

Conversion to bool​

operator bool();

Checks if the dimension is non-zero.

Returns:

  • bool: true if both x and y are non-zero, otherwise false.

Conversion to uint32_t​

operator uint32_t();

Converts the dimension to a 32-bit raw value.

Returns:

  • uint32_t: A raw representation of the dimension. The high 16 bits represent x, and the low 16 bits represent y.
