示例1: clear
void clear() {
SamplesIterator i, end = samples.end();
for (i = samples.begin(); i != end; ++i) {
// delete object pointed to by Sample* pointer
delete (*i);
}
samples.clear();
byNames.clear();
marker::manager.unref(markers);
}示例2: filter
void filter(const marker::Set& refMarkers) {
if (markers == NULL) {
throw invalid_argument("Markers in sample set are missing.");
}
// flag markers for removal
markers->filter(refMarkers);
if (samples.size() > 0) {
// Create copy of samples with only unflagged markers
// Shallow copy current samples (copy pointers)
Samples oldSamples = samples;
// clear current data
samples.clear();
byNames.clear();
// pre-allocate space
samples.resize(oldSamples.size());
for (size_t sampleIndex = 0; sampleIndex < oldSamples.size(); ++sampleIndex) {
// iterate through chromosomes
for (size_t chromIndex = 0; chromIndex < oldSamples[0]->size(); ++chromIndex) {
// resize chromosome to be as big as chromosome from old sample
samples[sampleIndex]->resizeChromosome(chromIndex, (*oldSamples[sampleIndex])[chromIndex].size());
}
}
// copy data from unflagged markers
const size_t chromEnd = markers->size();
vector<size_t> validMarkersCounts(chromEnd);
for (size_t chromIndex = 0; chromIndex < chromEnd; ++chromIndex) {
