Detailed Description

....................................................................... A struct for managing offsets read in from a scan offset file.

Member Function Documentation

void ScanCache::clearInterpolationContainers ( )

....................................................................... Empty the interpolation containers

void ScanCache::computeOffset ( ScanCacheOffset *  offset,
gcp::util::TimeVal &  mjd 
)

....................................................................... Compute the offset for the passed mjd

int ScanCache::empty ( )

....................................................................... Empty a cache.

void ScanCache::extend ( unsigned  index)

....................................................................... Add a new point to the interpolation containers

void ScanCache::extendInterpolation ( gcp::util::TimeVal &  mjd)

....................................................................... Extend the interpolation containers in preparation for the next evaluation

void ScanCache::fillInterpolationContainers ( unsigned  startIndex)

....................................................................... Fill the interpolation containers, starting from the passed index

void ScanCache::getNextOffset ( ScanCacheOffset *  offset,
gcp::util::TimeVal &  mjd 
)

....................................................................... Get the next set of offsets from the cache.

ScanMode ScanCache::getState ( gcp::util::TimeVal &  mjd)

....................................................................... Do whatever is appropriate to extend the interpolation containers in preparation for the next computation

int ScanCache::initialize ( unsigned int  in_ibody,
unsigned int  in_iend,
unsigned int  in_nreps,
unsigned int  in_msPerStep,
unsigned int  in_msPerSample,
bool  add 
)

....................................................................... Initialize cache object

bool ScanCache::nextStepEndsScan ( gcp::util::TimeVal &  mjd)

....................................................................... Return true if the next step will end the scan

bool ScanCache::nextStepIsBody ( gcp::util::TimeVal &  mjd)

....................................................................... Return true if the next step is part of the body segment

bool ScanCache::nextStepStartsNewIteration ( gcp::util::TimeVal &  mjd)

....................................................................... Return true if the next step is part of the body segment

void ScanCache::setUpForNewInterpolation ( gcp::util::TimeVal &  mjd,
unsigned  index 
)

....................................................................... Get the scan offsets and rates corresponding to this mjd

void ScanCache::setUpForNextIteration ( gcp::util::TimeVal &  mjd)

....................................................................... Get the scan offsets and rates corresponding to this mjd

void ScanCache::updateInterpolators ( gcp::util::TimeVal &  mjd)
