Detailed Description

template<typename T_Real, typename T_Gradient, typename T_Identifier, typename T_Position>
struct codi::ReadWriteTapeInterface< T_Real, T_Gradient, T_Identifier, T_Position >

Write a tape to a file using a writer from the codi::TapeWriterInterface. When reading a stored tape, create a primal or a Jacobian statement on the tape.

See codi::TapeWriterInterface and codi::TapeReaderInterface for details.

Template Parameters

T_Real	The computation type of a tape, usually chosen as ActiveType::Real.
T_Gradient	The gradient type of a tape usually, chosen as ActiveType::Gradient.
T_Identifier	The adjoint/tangent identification type of a tape, usually chosen as ActiveType::Identifier.
T_Position	Global tape position, usually chosen as Tape::Position.

Member Function Documentation

createStatementManual() [1/2]

template<typename T_Real, typename T_Gradient, typename T_Identifier, typename T_Position>

void codi::ReadWriteTapeInterface< T_Real, T_Gradient, T_Identifier, T_Position >::createStatementManual	(	Identifier const &	lhsIndex,
		Real const &	lhsValue,
		Config::ArgumentSize const &	nActiveValues,
		Identifier const *const	rhsIdentifiers,
		Config::ArgumentSize const &	nPassiveValues,
		Real const *const	rhsPrimals,
		Config::ArgumentSize const &	nConstants,
		Real const *const	rhsConstant,
		EvalHandle const &	evalHandle )

Initialize the statement and the rhs vectors from a file. It is especially important that the Identifiers are valid when using this method. This overload is used for Primal tapes.

createStatementManual() [2/2]

template<typename T_Real, typename T_Gradient, typename T_Identifier, typename T_Position>

void codi::ReadWriteTapeInterface< T_Real, T_Gradient, T_Identifier, T_Position >::createStatementManual	(	Real const &	lhsValue,
		Identifier &	lhsIndex,
		Config::ArgumentSize const &	size,
		Real const *	jacobians,
		Identifier const *	rhsIdentifiers )

Initialize the statement from a file. It is especially important that the lhsIndex is valid when using this method. This overload is used for Jacobian tapes.
