Class for iterating over a list of terms.

inline |
Default constructor.
Creates an uninitialised iterator, which can't be used before being assigned to, but is sometimes syntactically convenient.
| void Xapian::TermIterator::skip_to | ( | const std::string & | term | ) |
Advance the iterator to term term.
If the iteration is over an unsorted list of terms, then this method will throw Xapian::InvalidOperationError.
| term | The term to advance to. If this term isn't in the stream being iterated, then the iterator is moved to the next term after it which is. |
