Inheritance diagram for Xapian::TermIterator::Internal:
Public Member Functions | |
| virtual | ~Internal () |
| We have virtual methods and want to be able to delete derived classes using a pointer to the base class, so we need a virtual destructor. | |
| virtual Xapian::termcount | get_approx_size () const=0 |
| Return approximate size of this termlist. | |
| virtual void | accumulate_stats (Xapian::Internal::ExpandStats &stats) const |
| Collate weighting information for the current term. | |
| virtual std::string | get_termname () const=0 |
| Return the termname at the current position. | |
| virtual Xapian::termcount | get_wdf () const=0 |
| Return the wdf for the term at the current position. | |
| virtual Xapian::doccount | get_termfreq () const=0 |
| Return the term frequency for the term at the current position. | |
| virtual Xapian::termcount | get_collection_freq () const |
| Return the collection frequency for the term at the current position. | |
| virtual Internal * | next ()=0 |
| Advance the current position to the next term in the termlist. | |
| virtual Internal * | skip_to (const std::string &term) |
| Skip forward to the specified term. | |
| virtual bool | at_end () const=0 |
| Return true if the current position is past the last term in this list. | |
| virtual Xapian::termcount | positionlist_count () const=0 |
| Return the length of the position list for the current position. | |
| virtual Xapian::PositionIterator | positionlist_begin () const=0 |
| Return a PositionIterator for the current position. | |
Protected Member Functions | |
| Internal () | |
| Only constructable as a base class for derived classes. | |
Private Member Functions | |
| void | operator= (const Internal &) |
| Don't allow assignment. | |
| Internal (const Internal &) | |
| Don't allow copying. | |

| Xapian::TermIterator::Internal::Internal | ( | const Internal & | ) | [private] |
Don't allow copying.
| Xapian::TermIterator::Internal::Internal | ( | ) | [inline, protected] |
| Xapian::TermIterator::Internal::~Internal | ( | ) | [virtual] |
We have virtual methods and want to be able to delete derived classes using a pointer to the base class, so we need a virtual destructor.
Definition at line 31 of file termlist.cc.
| void Xapian::TermIterator::Internal::operator= | ( | const Internal & | ) | [private] |
Don't allow assignment.
| virtual Xapian::termcount Xapian::TermIterator::Internal::get_approx_size | ( | ) | const [pure virtual] |
Return approximate size of this termlist.
| void Xapian::TermIterator::Internal::accumulate_stats | ( | Xapian::Internal::ExpandStats & | stats | ) | const [virtual] |
Collate weighting information for the current term.
Definition at line 34 of file termlist.cc.
References Assert.
| virtual std::string Xapian::TermIterator::Internal::get_termname | ( | ) | const [pure virtual] |
Return the termname at the current position.
| virtual Xapian::termcount Xapian::TermIterator::Internal::get_wdf | ( | ) | const [pure virtual] |
Return the wdf for the term at the current position.
| virtual Xapian::doccount Xapian::TermIterator::Internal::get_termfreq | ( | ) | const [pure virtual] |
Return the term frequency for the term at the current position.
| Xapian::termcount Xapian::TermIterator::Internal::get_collection_freq | ( | ) | const [virtual] |
Return the collection frequency for the term at the current position.
This method is only implemented for subclasses of AllTermsList (and isn't currently used).

| virtual Internal* Xapian::TermIterator::Internal::next | ( | ) | [pure virtual] |
Advance the current position to the next term in the termlist.
The list starts before the first term in the list, so next() must be called before any methods which need the context of the current position.
| virtual Internal* Xapian::TermIterator::Internal::skip_to | ( | const std::string & | term | ) | [virtual] |
Skip forward to the specified term.
If the specified term isn't in the list, position ourselves on the first term after tname (or at_end() if no terms after tname exist).
| virtual bool Xapian::TermIterator::Internal::at_end | ( | ) | const [pure virtual] |
Return true if the current position is past the last term in this list.
| virtual Xapian::termcount Xapian::TermIterator::Internal::positionlist_count | ( | ) | const [pure virtual] |
Return the length of the position list for the current position.
| virtual Xapian::PositionIterator Xapian::TermIterator::Internal::positionlist_begin | ( | ) | const [pure virtual] |
Return a PositionIterator for the current position.
