Detailed Description

Linux desktop platform implementation.

This class provides an implementation of the IDesktopPlatform interface specifically for the Linux desktop environment. It handles platform-specific functionality related to Linux, such as creating a Vulkan surface using GLFW and managing the necessary resources for rendering on Linux.

Constructor & Destructor Documentation

◆ LinuxDesktopPlatform()

evan::LinuxDesktopPlatform::LinuxDesktopPlatform	(	const std::string &	name,
		const uint32_t	width,
		const uint32_t	height
	)

Constructor for LinuxDesktopPlatform.

Parameters

name	The name of the window.
width	The width of the window.
height	The height of the window. This constructor initializes the Linux desktop platform with the specified window parameters, setting up the necessary resources for rendering on Linux using Vulkan and GLFW.

Definition at line 13 of file LinuxDesktopPlatform.cpp.

Member Function Documentation

◆ createSurface()

VkSurfaceKHR evan::LinuxDesktopPlatform::createSurface ( VkInstance instance ) const

overridevirtual

Create a Vulkan surface for the Linux desktop platform.

Parameters

instance The Vulkan instance to use for creating the surface.

Returns: The created Vulkan surface. This method creates a Vulkan surface that is compatible with the Linux desktop platform, allowing rendered images to be presented on the screen. The implementation may involve using GLFW's functions to create a window surface that can be used with Vulkan on Linux.

Implements evan::IDesktopPlatform.

Definition at line 53 of file LinuxDesktopPlatform.cpp.

◆ getDefaultCacheRoot()

std::filesystem::path evan::LinuxDesktopPlatform::getDefaultCacheRoot ( ) const

overrideprotectedvirtual

Get the Linux cache root directory.

Returns: XDG_CACHE_HOME when set, ~/.cache otherwise, or an empty path when neither is available.

Implements evan::IPlatform.

Definition at line 72 of file LinuxDesktopPlatform.cpp.

◆ getRequiredInstanceExtensions()

std::vector< std::string > evan::LinuxDesktopPlatform::getRequiredInstanceExtensions ( ) const

overridevirtual

Get the required instance extensions for the Linux desktop platform.

Returns: A vector of strings representing the required instance extensions for the Linux desktop platform.

This method retrieves the necessary Vulkan instance extensions required for the Linux desktop platform, which may include extensions for window surface creation and other platform-specific features related to Vulkan on Linux.

Implements evan::IDesktopPlatform.
