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 279 of file inmemory_database.cc.

◆ at_end()

bool InMemoryTermList::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 327 of file inmemory_database.cc.

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

Referenced by accumulate_stats(), get_termfreq(), get_termname(), get_wdf(), and next().

◆ get_approx_size()

Xapian::termcount InMemoryTermList::get_approx_size ( ) const

virtual

Return approximate size of this termlist.

Implements Xapian::TermIterator::Internal.

Definition at line 272 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 260 of file inmemory_database.cc.

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

Referenced by accumulate_stats().

◆ get_termname()

string InMemoryTermList::get_termname ( ) const

virtual

Return the termname at the current position.

Implements Xapian::TermIterator::Internal.

Definition at line 291 of file inmemory_database.cc.

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

◆ 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 251 of file inmemory_database.cc.

References Assert, at_end(), db, InMemoryDatabase::is_closed(), 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: 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.
