The data type from the AD tool for the identification of AD variables.

◆ ModifiedType

typedef double medi::StaticADToolInterface::ModifiedType

The type that is send through the modified buffers.

◆ PrimalType

typedef double medi::StaticADToolInterface::PrimalType

The data type used for the floating point data.

◆ Type

Member Function Documentation

◆ clearIndex()

static void medi::StaticADToolInterface::clearIndex ( Type & value )

static

Delete the index in a buffer such that the buffer can be overwritten.

Parameters

[in,out] value The AD value in the buffer.

◆ createIndex()

static void medi::StaticADToolInterface::createIndex	(	Type &	value,
		IndexType &	index
	)

static

Create an index for the given item in the buffer.

Parameters

[in,out]	value	The AD value in the buffer.
[out]	index	The index for the value.

◆ getFromModifyBuffer()

static void medi::StaticADToolInterface::getFromModifyBuffer	(	const ModifiedType &	modValue,
		Type &	value
	)

static

Copies the nescessary data from the received MeDiPack buffer into the user buffer.

Parameters

[in]	modValue	The value in the modified buffer
[out]	value	The value in the user buffer.

◆ getIndex()

static IndexType medi::StaticADToolInterface::getIndex ( const Type & value )

static

Get the AD identifier for this value.

Parameters

[in] value The AD value.

Returns: The identifier for the AD value.

◆ getValue()

static PrimalType medi::StaticADToolInterface::getValue ( const Type & value )

static

Get the primal floating point value of the AD value.

Parameters

[in] value The AD value.

Returns: The primal floating point value that is represented by the AD value.

◆ registerValue()

static void medi::StaticADToolInterface::registerValue	(	Type &	value,
		PrimalType &	oldPrimal,
		IndexType &	index
	)

static

Register an AD value on the receiving side of the communication.

Parameters

[in,out]	value	The AD value in the user buffer on the receiving side.
[out]	oldPrimal	The old primal value that was overwritten by this value.
[in,out]	index	The identifier registered for the old value. This value may be set here or already be the value from createIndex.

◆ setIntoModifyBuffer()

static void medi::StaticADToolInterface::setIntoModifyBuffer	(	ModifiedType &	modValue,
		const Type &	value
	)

static

Copies the nescessary data from the user buffer into the buffer crated by MeDiPack.

Parameters

[out]	modValue	The value in the modified buffer
[in]	value	The value in the user buffer.
