Function Documentation

void fromSheetsToSlicesParity	(	const vector< LaneValue > &	paritySheets,
		vector< RowValue > &	paritySlices
	)

This function converts the parity of a state expressed as a vector of parities of each sheet into a vector of parities of each slice.

Precondition:

paritySlices must be initialized with the correct size (lane size).

Parameters:

	paritySheets	The parity as a vector of lanes.
	paritySlices	The parity as a vector of rows.

void fromSlicesToSheetsParity	(	const vector< RowValue > &	paritySlices,
		vector< LaneValue > &	paritySheets
	)

This function converts the parity of a state expressed as a vector of parities of each slice into a vector of parities of each sheet.

Parameters:

	paritySlices	The parity as a vector of rows.
	paritySheets	The parity as a vector of lanes.

void getParity	(	const vector< LaneValue > &	state,
		vector< LaneValue > &	parity
	)

This function computes the parity of a state, sheet per sheet, and returns it in a vector of lane values.

Parameters:

	state	The value of the state given as a vector of lanes.
	parity	The parity of state as a vector of 5 lane values.

void getParity	(	const vector< SliceValue > &	state,
		vector< RowValue > &	parity
	)

This function computes the parity of a state, slice per slice, and returns it in a vector of row values.

Parameters:

	state	The value of the state given as a vector of slices.
	parity	The parity of state as a vector of row values.

PackedParity getParity

(

const vector< SliceValue > &

state

)

This function computes the parity of a state, and returns it in a PackedParity.

Parameters:

state

The value of the state given as a vector of slices.

Returns:

The parity of the state.

RowValue getParity

(

SliceValue

slice

)

This function computes the parity of a slice.

Parameters:

slice

The value of a slice.

Returns:

The parity of the given slice value.

PackedParity packParity

(

const vector< RowValue > &

parity

)

This function converts from a vector of parity of each slice to a PackedParity value.

Parameters:

parity

The parity of a state as vector of row values.

Returns:

The parity of a state as a PackedParity value.

void unpackParity	(	PackedParity	packedParity,
		vector< RowValue > &	parity,
		unsigned int	laneSize
	)

This function converts from a PackedParity value to a vector of parity of each slice.

Parameters:

	packedParity	The parity of a state as a PackedParity value.
	parity	The parity of a state as a vector of row values.
	laneSize	The number of slices.
