Detailed Description

template<typename T_TapeTypes>
struct codi::PrimalValueLinearTape< T_TapeTypes >

Final implementation for a primal value tape with a linear index management.

This class implements the interface methods from the PrimalValueBaseTape.

Template Parameters

T_TapeTypes JacobianTapeTypes definition.

Member Typedef Documentation

◆ TapeTypes

template<typename T_TapeTypes >

using codi::PrimalValueLinearTape< T_TapeTypes >::TapeTypes

Initial value:

 
 T_TapeTypes

See PrimalValueLinearTape.

Member Function Documentation

◆ clearAdjoints()

template<typename T_TapeTypes >

void codi::PrimalValueLinearTape< T_TapeTypes >::clearAdjoints	(	Position const &	start,
		Position const &	end,
		AdjointsManagement	adjointsManagement = AdjointsManagement::Automatic )

inline

Clear all adjoints that would be set in a tape evaluation from start to end. It has to hold start >= end.

Automatic adjoints management involves locking, see AdjointsManagement for details.
Implementation: Automatic adjoints management has no effect. Primal value tapes do not implement adjoints locking.
