示例1: write_stateset
// Write a whole StateSet in one go. The optional argument sort_order can be
// given to write states in an order different from their order in the
// StateSet (for example, in order of increasing energy).
void Datafile::write_stateset(StateSet const& stateset, int step, std::list<size_t> const* sort_order) {
hsize_t states_cur_size[2];

try {
ensure_states_data();
ensure_state_history_data();
// calculate current size of states_data
states_data.getSpace().getSimpleExtentDims(states_cur_size);
// new slot for states will be same as states_cur_size[0]
const hsize_t new_slot = states_cur_size[0];
state_history_pair pair;
pair.step = step;
pair.index = static_cast<int>(new_slot);
// calculate current size of state_history_data and extend by one
