inline void setOperation(const Operation sfail, const Operation zfail, const Operation zpass)

set the operations to apply when the various stencil and depth tests fail or pass. First parameter is to control the operation when the stencil test fails. The second parameter is to control the operation when the stencil test passes, but depth test fails. The third parameter controls the operation when both the stencil test and depth pass. Ordering of parameter is the same as if using glStencilOp(,,).

get the operation when the stencil test fails

get the operation when the stencil test passes but the depth test fails

inline const Operation getStencilPassAndDepthPassOperation() const
