Detailed Description

template<typename Bit>
class oglplus::Bitfield< Bit >

This template serves as a wrapper for OpenGL bitfields.

Applications rarely need to use this class directly. Instantiations of this template are used as types for parameters in functions taking bitfields based on strongly-type enumerations. When constructing a bitfield the application simply passes the enumerated value or a combination of enumerated values using the bitwise-or operator or initializer list. For example:

Context gl;
gl.Clear(ClearBit::ColorBuffer);
gl.Clear(ClearBit::ColorBuffer|ClearBit::DepthBuffer|ClearBit::StencilBuffer);
gl.Clear({ClearBit::ColorBuffer});
gl.Clear({ClearBit::ColorBuffer, ClearBit::DepthBuffer});
gl.Clear({ClearBit::ColorBuffer, ClearBit::StencilBuffer});
