Detailed Description

template<typename T>
class gf::BufferRef< T >

A reference to a modifiable buffer and its size.

This class stores a pointer to a buffer and its size. It can be built from various inputs: std::vector, std::array, static array, pointer and size.

Parameters

data	A pointer to a buffer
size	The number of elements in the buffer

template<typename T >
