Detailed Description

template<typename T_Func, typename T_Type, typename T_InputStore = std::vector<T_Type>, typename T_OutputStore = std::vector<T_Type>>
struct codi::EvaluationHandleReverseJacobianTapes< T_Func, T_Type, T_InputStore, T_OutputStore >

Implementation for Jacobian reverse mode CoDiPack types of EvaluationHandleBase.

This tape re-records the logic behind the function object for every forward and reverse tape evaluations. Primal evaluations are not recorded.

The class performs no resizing of the vectors. The initial sizes need to be adequate for all calls to the function object that the user will perform.

Template Parameters

T_Func	The type of the function object which defines the evaluation logic.
T_Type	The CoDiPack type that is used for the derivative evaluation.
T_InputStore	Vector used for the storage of input arguments.
T_OutputStore	Vector used for the storage of output arguments.
