示例1: readFromStream
void RewardMappingTools::readFromStream(istream& in, ProbabilisticRewardMapping& rewards)
throw (IOException)
{
try
{
DataTable* data = DataTable::read(in, "\t", true, -1);
vector<string> ids = data->getColumn(0);
data->deleteColumn(0); // Remove ids
data->deleteColumn(0); // Remove means
// Now parse the table:
size_t nbSites = data->getNumberOfColumns();
rewards.setNumberOfSites(nbSites);
size_t nbBranches = data->getNumberOfRows();
for (size_t i = 0; i < nbBranches; i++)
{
int id = TextTools::toInt(ids[i]);

for (size_t j = 0; j < nbSites; j++)
{

}
}
// Parse the header:
for (size_t i = 0; i < nbSites; i++)
