Member Function Documentation
| bool VectorTermList::at_end | ( | ) | const [inline, virtual] |
Return true if the current position is past the last term in this list.
Implements Xapian::TermIterator::Internal.
Definition at line 99 of file vectortermlist.h.
References before_start, offset, and terms.
| Xapian::termcount VectorTermList::get_approx_size | ( | ) | const [inline, virtual] |
Return approximate size of this termlist.
Implements Xapian::TermIterator::Internal.
Definition at line 54 of file vectortermlist.h.
References terms.
| Xapian::doccount VectorTermList::get_termfreq | ( | ) | const [inline, virtual] |
Return the term frequency for the term at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 71 of file vectortermlist.h.
| string VectorTermList::get_termname | ( | ) | const [inline, virtual] |
Return the termname at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 59 of file vectortermlist.h.
References Assert, before_start, offset, and terms.
| Xapian::termcount VectorTermList::get_wdf | ( | ) | const [inline, virtual] |
Return the wdf for the term at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 65 of file vectortermlist.h.
References Assert, before_start, offset, and terms.
| TermList* VectorTermList::next | ( | ) | [inline, virtual] |
next() causes the TermList to move to the next term in the list.
It must be called before any other methods. If next() returns a non-zero pointer P, then the original termlist should be deleted, and the original pointer replaced with P. In a leaf TermList, next() will always return 0.
Implements Xapian::TermIterator::Internal.
Definition at line 82 of file vectortermlist.h.
References Assert, at_end(), before_start, and offset.
| Xapian::PositionIterator VectorTermList::positionlist_begin | ( | ) | const [inline, virtual] |
Return a PositionIterator for the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 103 of file vectortermlist.h.
| Xapian::termcount VectorTermList::positionlist_count | ( | ) | const [inline, virtual] |
Return the length of the position list for the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 107 of file vectortermlist.h.
| TermList* VectorTermList::skip_to | ( | const string & | term | ) | [inline, 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).
Implements Xapian::TermIterator::Internal.
