acquireLock()

AccessLock< std::mutex > fge::manager::BaseManager< vulkan::Shader, DataBlock >::acquireLock ( ) const

nodiscardinherited

Acquire a AccessLock, with the manager mutex.

In order to use iterators, you have to acquire a unique lock from this function. The lock is not differed and will lock the mutex.

Returns

A AccessLock bound to this mutex

begin()

BaseManager< vulkan::Shader, DataBlock >::Map::const_iterator fge::manager::BaseManager< vulkan::Shader, DataBlock >::begin ( AccessLock< std::mutex > const & lock ) const

nodiscardinherited

Get the "begin" iterator of the manager.

You have to provide a valid reference to a AccessLock acquired with the function AcquireLock(). This function will throw if one of this is not respected :

• The mutex pointer of the lock does not correspond to this mutex.

Parameters

lock	A AccessLock bound to this mutex

Returns

The "begin" iterator of the texture manager

end()

BaseManager< vulkan::Shader, DataBlock >::Map::const_iterator fge::manager::BaseManager< vulkan::Shader, DataBlock >::end ( AccessLock< std::mutex > const & lock ) const

nodiscardinherited

Get the "end" iterator of the manager.

begin()

Parameters

lock	A AccessLock bound to this mutex

Returns

The "end" iterator of the manager

getBadElement()

BaseManager< vulkan::Shader, DataBlock >::DataBlockPointer const & fge::manager::BaseManager< vulkan::Shader, DataBlock >::getBadElement ( ) const

nodiscardinherited

Get the "bad" element.

A bad element is a "valid" default resource that is returned when the requested resource is not found. return The "bad" element

getElement()

BaseManager< vulkan::Shader, DataBlock >::DataBlockPointer fge::manager::BaseManager< vulkan::Shader, DataBlock >::getElement ( std::string_view name ) const

nodiscardinherited

Get the resource with the given name.

Parameters

name	The name of the resource to get

Returns

The resource with the given name or the bad resource if not found

initialize()

bool fge::shader::ShaderManager::initialize ( )

overridevirtual

Initialize the shader manager.

A bad shader is created with this function, it is used when a shader is not found. You also have to provide a default vertex and fragments shaders.

3 default shaders are created : FGE_SHADER_DEFAULT_VERTEX : The default vertex shader (in shaderResources.hpp gDefaultVertexShader) FGE_SHADER_DEFAULT_NOTEXTURE_FRAGMENT : The default fragment shader with no texture attached (in shaderResources.hpp gDefaultFragmentShader) FGE_SHADER_DEFAULT_FRAGMENT : The default fragment shader (in shaderResources.hpp gDefaultFragmentTextureShader)

Returns

true if the shader manager is correctly initialized, false otherwise

Implements fge::manager::BaseManager< vulkan::Shader, DataBlock >.

loadFromFile()

bool fge::shader::ShaderManager::loadFromFile	(	std::string_view	name,
		std::filesystem::path	path,
		fge::vulkan::Shader::Type	type,
		ShaderInputTypes	input,
		bool	debugBuild = false )

Load a shader from a file.

Parameters

name	The name of the shader to load
path	The path of the file to load
type	The shader type
input	The input file type
debugBuild	If the input must be compiled into SPIR-V, then it will be compiled with debug symbols

Returns

true if the shader was loaded, false otherwise

loadFromMemory()

bool fge::shader::ShaderManager::loadFromMemory	(	std::string_view	name,
		void const *	data,
		int	size,
		fge::vulkan::Shader::Type	type,
		ShaderInputTypes	input,
		bool	debugBuild = false )

Load a shader from the memory.

Warning

if you pass a SPIR-V binary data, the size must be a multiple of 4.

Parameters

name	The name of the shader to load
data	The data address to load
size	The data size to load
type	The shader type
input	The input file type
debugBuild	If the input must be compiled into SPIR-V, then it will be compiled with debug symbols

Returns

true if the shader was loaded, false otherwise

push()

bool fge::manager::BaseManager< vulkan::Shader, DataBlock >::push ( std::string_view name, DataBlockPointer block )

inherited

Add a user handled resource.

Parameters

name	The name of the texture to add
block	The block data to add

Returns

true if the resource was added, false otherwise

size()

std::size_t fge::manager::BaseManager< vulkan::Shader, DataBlock >::size ( ) const

nodiscardinherited

Get the number of elements in the manager.

return The number of elements in the manager without the "bad" element
