Public Member Functions inherited from Xapian::TermIterator::Internal | |
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. More... | |
virtual const std::vector< Xapian::termpos > * | get_vector_termpos () const |
Get pointer to vector<termpos> if that's the internal representation. More... | |

Return the wdf for the term at the current position.

|
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.

Return a PositionIterator for the current position.

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).

protected |
The current term for left and right respectively.
Until next() is first called, these will be empty strings. Once next() has been called, they won't be empty (since the empty string isn't a valid term).
