Member Function Documentation

◆ accumulate_stats()

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

virtual

Collate weighting information for the current term.

Reimplemented from Xapian::TermIterator::Internal.

Definition at line 282 of file inmemory_database.cc.

References Xapian::Internal::ExpandStats::accumulate(), Assert, db, document_length, end, InMemoryDatabase::get_doccount(), get_termfreq(), get_wdf(), InMemoryDatabase::is_closed(), pos, Xapian::TermIterator::Internal::shard_index, started, and InMemoryDatabase::throw_database_closed().

◆ get_approx_size()

Xapian::termcount InMemoryTermList::get_approx_size ( ) const

virtual

Return approximate size of this termlist.

Implements Xapian::TermIterator::Internal.

Definition at line 275 of file inmemory_database.cc.

References db, InMemoryDatabase::is_closed(), terms, and InMemoryDatabase::throw_database_closed().

◆ get_termfreq()

Xapian::doccount InMemoryTermList::get_termfreq ( ) const

virtual

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

Implements Xapian::TermIterator::Internal.

Definition at line 263 of file inmemory_database.cc.

References Assert, db, end, InMemoryDatabase::get_freqs(), InMemoryDatabase::is_closed(), pos, started, and InMemoryDatabase::throw_database_closed().

Referenced by accumulate_stats().

◆ get_wdf()

Xapian::termcount InMemoryTermList::get_wdf ( ) const

virtual

Return the wdf for the term at the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 254 of file inmemory_database.cc.

References Assert, db, end, InMemoryDatabase::is_closed(), pos, started, and InMemoryDatabase::throw_database_closed().

Referenced by accumulate_stats().

◆ next()

TermList * InMemoryTermList::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: Normally returns NULL to indicate success. If the end has been reached, returns this; if another 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.

Definition at line 294 of file inmemory_database.cc.

References Assert, Xapian::TermIterator::Internal::current_term, db, end, InMemoryDatabase::is_closed(), pos, started, and InMemoryDatabase::throw_database_closed().

◆ positionlist_begin()

PositionList * InMemoryTermList::positionlist_begin ( ) const

virtual

Return PositionList for the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 334 of file inmemory_database.cc.

References db, did, InMemoryDatabase::is_closed(), InMemoryDatabase::open_position_list(), and InMemoryDatabase::throw_database_closed().

◆ positionlist_count()

Xapian::termcount InMemoryTermList::positionlist_count ( ) const

virtual

Return the length of the position list for the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 327 of file inmemory_database.cc.

References db, did, InMemoryDatabase::is_closed(), InMemoryDatabase::positionlist_count(), and InMemoryDatabase::throw_database_closed().

◆ skip_to()

TermList * InMemoryTermList::skip_to ( std::string_view term )

virtual

Skip forward to the specified term.

If the specified term isn't in the list, position ourselves on the first term after term.

Returns: Normally returns NULL to indicate success. If no terms after term exist, returns this; if another 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.
