T_return_type stan::math::operands_and_partials< Op1, Op2, Op3, Op4, Op5, Op6, Op7, Op8, fvar< Dx > >::build ( Dx  value )

inline

Build the node to be stored on the autodiff graph.

This should contain both the value and the tangent.

For scalars, we don't calculate any tangents. For reverse mode, we end up returning a type of var that will calculate the appropriate adjoint using the stored operands and partials. Forward mode just calculates the tangent on the spot and returns it in a vanilla fvar.

Parameters

value

the return value of the function we are compressing

Returns

the value with its derivative
