Detailed Description

template<typename T, typename... Args>
class Shader< T, Args >

The main templated base class for all shaders that do not use textures.

The template arguments are the types of the shader's uniforms. This allows compile time checks for the number of arguments when setting the name of the shader arguments.

Constructor & Destructor Documentation

◆ Shader()

template<typename T , typename... Args>

Shader< T, Args >::Shader ( )

inline

Constructor.

Adds the static kill function of this shader to the list of all kill function, which is used for the debugging feature of reloading all shaders.

Member Function Documentation

◆ assignTextureUnit()

template<typename T , typename... Args>

template<typename... T1>

void Shader< T, Args >::assignTextureUnit	(	GLuint	index,
		const char *	uniform,
		T1...	rest
	)

inline

Variadic top level/public interface.

It does the calls to glUseProgram and uses assignTextureUnitNoUse() in recursion to avoid unnecessary calls to glUseProgram.

Parameters

index	Index of the texture.
uniform	Uniform name.

◆ assignUniforms()

template<typename T , typename... Args>

template<typename... U>

void Shader< T, Args >::assignUniforms ( U... rest )

inlineprotected

This variadic template collects all names of uniforms in a std::vector.

It used assignUnfiromsImpl for the actual recursive implementation.

◆ assignUniformsImpl()

template<typename T , typename... Args>

template<typename... U>

void Shader< T, Args >::assignUniformsImpl	(	const char *	name,
		U...	rest
	)

inlineprivate

Recursive implementation of assignniforms.

It collects the unfirom locations in m_uniform, then recursing.

Parameters

name	Name of the uniform.

◆ printFileList()

template<typename T , typename... Args>

template<typename ... Types>

void Shader< T, Args >::printFileList	(	GLint	shader_type,
		const char *	filepath,
		Types ...	args
	)

inlineprotected

Variadic template to print a list of file names.

Parameters

shader_type	Ignored (used since the variadic calling function has this parameter).
filepath	Name of the file to print.

The documentation for this class was generated from the following file:
