Member Function Documentation

◆ accumulate_stats()

void MultiTermList::accumulate_stats ( Xapian::Internal::ExpandStats & stats ) const

virtual

Collate weighting information for the current term.

Reimplemented from Xapian::TermIterator::Internal.

Definition at line 50 of file multi_termlist.cc.

References Xapian::TermIterator::Internal::accumulate_stats(), and tl.

◆ at_end()

bool MultiTermList::at_end ( ) const

virtual

Return true if the current position is past the last term in this list.

Implements Xapian::TermIterator::Internal.

Definition at line 81 of file multi_termlist.cc.

References Xapian::TermIterator::Internal::at_end(), and tl.

◆ get_approx_size()

Xapian::termcount MultiTermList::get_approx_size ( ) const

virtual

Return approximate size of this termlist.

Implements Xapian::TermIterator::Internal.

Definition at line 44 of file multi_termlist.cc.

References Xapian::TermIterator::Internal::get_approx_size(), and tl.

◆ get_termfreq()

Xapian::doccount MultiTermList::get_termfreq ( ) const

virtual

Return the term frequency for the term at the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 66 of file multi_termlist.cc.

References db, Xapian::Database::get_termfreq(), Xapian::TermIterator::Internal::get_termname(), and tl.

◆ get_termname()

string MultiTermList::get_termname ( ) const

virtual

Return the termname at the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 56 of file multi_termlist.cc.

References Xapian::TermIterator::Internal::get_termname(), and tl.

◆ get_wdf()

Xapian::termcount MultiTermList::get_wdf ( ) const

virtual

Return the wdf for the term at the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 61 of file multi_termlist.cc.

References Xapian::TermIterator::Internal::get_wdf(), and tl.

◆ next()

TermList * MultiTermList::next ( )

virtual

Advance the current position to the next term in the termlist.

The list starts before the first term in the list, so next(), skip_to() or check() must be called before any methods which need the context of the current position.

Returns: If a non-NULL pointer is returned, then the caller should substitute the returned pointer for its pointer to us, and then delete us. This "pruning" can only happen for a non-leaf subclass of this class.

Implements Xapian::TermIterator::Internal.
