Description:

/** * @brief VirtualBufferObject is a specific resources for opengl, this load the data directly in the graphic card ad keep these inside */

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(int32_t id);

get the real openGL ID.

Return: the Ogl id reference of this VBO.

---

getRefBuffer ()

std::vector<float> & getRefBuffer(int32_t id);

get a reference on hte buffer data for this VBO.

Parameter [input]: id Id of the buffer requested
Return: A reference on the data.

---

pushOnBuffer ()

void pushOnBuffer(int32_t id,
                  const vec3 & data);

push data on a buffer with a custum type :

Parameter [input]: id Id of the buffer requested.
Parameter [input]: data Direct data that might be set.

---

getOnBufferVec3 ()

vec3 getOnBufferVec3(int32_t id,
                     int32_t elementID);

---

sizeOnBufferVec3 ()

int32_t sizeOnBufferVec3(int32_t id);

---

pushOnBuffer ()

void pushOnBuffer(int32_t id,
                  const vec2 & data);

push data on a buffer with a custum type :

Parameter [input]: id Id of the buffer requested.
Parameter [input]: data Direct data that might be set.

---

getOnBufferVec2 ()

vec2 getOnBufferVec2(int32_t id,
                     int32_t elementID);

---

sizeOnBufferVec2 ()

int32_t sizeOnBufferVec2(int32_t id);

---

retreiveData ()

void retreiveData(void);

get the data from the graphic card.

---

flush ()

void flush(void);

Send the data to the graphic card.

---

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::VirtualBufferObject * keep(int32_t _number);

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

Parameter [input]: _number Number of VBO needed
Return: pointer on the resource or NULL if an error occured.

---

ewol::release ()

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

release the keeped resources

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

---

ewol::VirtualBufferObject ()

VirtualBufferObject(int32_t _number);

Constructor of this VBO.

Parameter [input]: accesMode Acces mode : ???

---

ewol::~VirtualBufferObject ()

~VirtualBufferObject(void);

Destructor of this VBO.
