Description:

/** * @brief Shader is a specific resources for opengl, used only in @ref Program. This are components of the renderer pipe-line */

Detail:

getType ()

const char * getType(void);

Generic function that get the resouces name of his type.

Return: The define char of his name.

---

getGL_ID ()

GLuint getGL_ID(void);

get the opengl reference id of this shader.

Return: The opengl id.

---

getShaderType ()

GLenum getShaderType(void);

get the opengl type of this shader.

Return: The type of this loaded shader.

---

updateContext ()

void updateContext(void);

This load/reload the data in the opengl context, needed when removed previously.

---

removeContext ()

void removeContext(void);

remove the data from the opengl context.

---

removeContextToLate ()

void removeContextToLate(void);

Special android spec! It inform us that all context is removed and after notify us...

---

reload ()

void reload(void);

Relode the shader from the file. used when a request of resouces reload is done.
Notes: this is really usefull when we tested the new themes or shader developpements.

---

ewol::keep ()

static ewol::Shader * keep(const std::string & _filename);

keep the resource pointer.
Notes: Never free this pointer by your own...

Parameter [input]: _filename Name of the openGL Shader.
Return: pointer on the resource or NULL if an error occured.

---

ewol::release ()

static void release(ewol::Shader * & _object);

release the keeped resources

Parameter [input] [output]: reference on the object pointer

---

ewol::Shader ()

Shader(const std::string & _filename);

Contructor of an opengl Shader

Parameter [input]: filename Standard file name format. see

---

ewol::~Shader ()

~Shader(void);

Destructor, remove the current Shader
