Public Functions

explicit Buffer(Type type)

inline Buffer()

~Buffer() = default

inline Type type() const

inline Usage usage() const

inline void setUsage(const Usage u)

inline void createOnce(): Calls create() only if the buffer has not been created yet.

inline bool initialized() const

inline void destroy(): Automatically called upon destructor, no need for the user to call it in normal situations.

inline void bind()

inline void unbind()

inline unsigned int bufferId() const

inline void allocate(const void *data, int byteCount): Reserves byteCount bytes in the buffer and copy to it the provided data. create() and bind() must be called before using this method.
