Function Documentation

getUnixNanoseconds()

uint64_t etsi_its_rtcmem_ts_msgs::access::getUnixNanoseconds ( const RTCMEM & rtcmem, const uint64_t unix_nanoseconds_estimate )

inline

Get the unix nanoseconds from a RTCMEM object.

Parameters

rtcmem	given RTCMEM object
unix_nanoseconds_estimate	unix timestamp to derive the current year from in nanoseconds

Returns

uint64_t unix timestamp according to the stored MinuteOfTheYear in nanoseconds

Definition at line 101 of file rtcmem_ts_utils.h.

getUnixNanosecondsFromMinuteOfTheYear()

uint64_t etsi_its_rtcmem_ts_msgs::access::getUnixNanosecondsFromMinuteOfTheYear ( const MinuteOfTheYear & moy, const uint64_t unix_nanoseconds_estimate )

inline

Get the unix nanoseconds from a MinuteOfTheYear object.

Parameters

moy	given MinuteOfTheYear object
unix_nanoseconds_estimate	unix timestamp to derive the current year from in nanoseconds

Returns

uint64_t unix timestamp according to the given MinuteOfTheYear in nanoseconds

Definition at line 75 of file rtcmem_ts_utils.h.

getUnixNanosecondsFromRTCMcorrections()

uint64_t etsi_its_rtcmem_ts_msgs::access::getUnixNanosecondsFromRTCMcorrections ( const RTCMcorrections & rtcm, const uint64_t unix_nanoseconds_estimate )

inline

Get the unix nanoseconds from a RTCMcorrections object.

Parameters

rtcm	given RTCMcorrections object
unix_nanoseconds_estimate	unix timestamp to derive the current year from in nanoseconds

Returns

uint64_t unix timestamp according to the stored MinuteOfTheYear in nanoseconds

Definition at line 89 of file rtcmem_ts_utils.h.

getUnixSecondsOfYear()

uint64_t etsi_its_rtcmem_ts_msgs::access::getUnixSecondsOfYear ( const uint64_t unixSecond )

inline

Get the unix seconds of the beginning of a year that corresponds to a given unix timestamp.

Parameters

unixSecond

timestamp that defines the year for that the unix seconds for the beginning of the year should be derived

Returns

uint64_t unix seconds of the beginning of the year

Definition at line 55 of file rtcmem_ts_utils.h.

interpretLatitudeInDegrees()

double etsi_its_rtcmem_ts_msgs::access::interpretLatitudeInDegrees ( const Latitude & lat )

inline

Convert Latitude integer representation into degrees.

Value is encoded in 1e-7 degrees. If UNAVAILABLE, returns NaN.

Parameters

lat	Latitude object to interpret

Returns

double latitude in degrees or NaN if unavailable

Definition at line 114 of file rtcmem_ts_utils.h.

interpretLongitudeInDegrees()

double etsi_its_rtcmem_ts_msgs::access::interpretLongitudeInDegrees ( const Longitude & lon )

inline

Convert Longitude integer representation into degrees.

Value is encoded in 1e-7 degrees. If UNAVAILABLE, returns NaN.

Parameters

lon	Longitude object to interpret

Returns

double longitude in degrees or NaN if unavailable
