void create()

Actually create the buffer, destroying any previously existing buffer.

Call after setting the type and usage.

See also:


void createOnce()

Calls create() only if the buffer has not been created yet.

void destroy()

Automatically called upon destructor, no need for the user to call it in normal situations.

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.
