Detailed Description

template<class BINTYPE, typename DIMTYPE>
class FST::Subset< BINTYPE, DIMTYPE >::Feature_Range

Read-only forward range over feature indices.

Returned by selected_features()/temporary_features(). Unlike the deprecated get*Feature() cursor pairs the range owns its complete iteration state: nested and early-exited loops are safe and the Subset stays untouched. Usage: for(DIMTYPE f : sub->selected_features()) {...} The range holds a raw pointer to the Subset and reads its markers lazily, so it must not outlive the Subset, and the selection must not be modified while a range is being iterated.

Member Enumeration Documentation

Kind

template<class BINTYPE, typename DIMTYPE>

enum FST::Subset::Feature_Range::Kind

Which raw features a Feature_Range/iterator matches.

Enumerator
SELECTED	features with a positive raw marker (selected, frozen, or under traversal; matches get_d_raw(), not get_d() – see selected_features())
TEMPORARY	features currently marked tmp_id_traverse by an in-progress getFirstCandidateSubset()/getNextCandidateSubset() traversal (see temporary_features())
