Function Documentation

size_t calculate_fvector_total_size

(

int

_size

)

Calculates total # of bytes that are used by FVector.

Parameters:

[in]

_size

# of elements (dimension) in FVector /return size of the FVector in bytes

size_t calculate_svector_total_size

(

int

_size

)

Calculates total # of bytes that are used by SVector.

Parameters:

[in]

_size

# of elements in SVector

Returns:

size of the SVector in bytes

size_t write_fvector_bin_psql_double	(	void *	out,
		size_t	max_size,
		int	_size,
		double *	ddata
	)

Writes given Fvector as binary data.

Parameters:

[out]	out	data pointer that FVector will be written to
[in]	max_size	maximum size of the data pointer (out)
[in]	_size	# of elements in the FVector
[in]	ddata	FVector data

Returns:

# of bytes that are written to out data

size_t write_svector_bin_psql_pair	(	void *	out,
		size_t	max_size,
		int	_size,
		Pair *	ddata
	)

Writes given Svector as binary data.

Parameters:

[out]	out	data pointer that SVector will be written to
[in]	max_size	maximum size of the data pointer (out)
[in]	_size	# of elements in the SVector
[in]	ddata	SVector data

Returns:

# of bytes that are written to out data
