Checksum() [1/2]

template<class C >

uint32 pcl::Checksum ( const C &  data )

inline

Returns the standard checksum value for a container.

Parameters

data	Reference to a container whose standard checksum will be calculated. The checksum number will be generated for the current data bytes in this container instance.

Checksum() [2/2]

size_type PCL_FUNC pcl::Checksum ( const void *  data, size_type  length  )

inline

Returns the standard checksum value calculated for a data sequence. The returned value is the total number of bits set in the sequence of input data bytes.

Parameters

data	Address of the first byte in the data sequence.
length	Length in bytes of the data sequence.

CRC32() [1/2]

template<class C >

uint32 pcl::CRC32 ( const C &  data )

inline

Returns the CRC-32 error-detecting code for a container.

Parameters

data	Reference to a container whose CRC-32 checksum will be calculated. The checksum code will be generated for the current data bytes in this container instance.

CRC32() [2/2]

uint32 PCL_FUNC pcl::CRC32	(	const void *	data,
		size_type	length
	)

Returns the CRC-32 error-detecting code calculated for a data sequence.

Parameters

data	Address of the first byte in the data sequence.
length	Length in bytes of the data sequence.
