Function Documentation

decodeDouble()

double lsst::sphgeom::decodeDouble ( uint8_t const *  buffer )

inline

decodeDouble extracts an IEEE double from the 8 byte little-endian byte sequence in buffer.

decodeU64()

std::uint64_t lsst::sphgeom::decodeU64 ( uint8_t const *  buffer )

inline

decodeU64 extracts an uint64 from the 8 byte little-endian byte sequence in buffer.

encodeDouble()

void lsst::sphgeom::encodeDouble ( double  item, std::vector< uint8_t > &  buffer  )

inline

encodeDouble appends an IEEE double in little-endian byte order to the end of buffer.

encodeU64()

void lsst::sphgeom::encodeU64 ( std::uint64_t  item, std::vector< uint8_t > &  buffer  )

inline

encodeU64 appends an uint64 in little-endian byte order to the end of buffer.
