Class for iterating over a list of terms.

## Constructor & Destructor Documentation

Xapian::PostingIterator::PostingIterator | ( |  | ) |

Creates an uninitialised iterator, which can't be used before being assigned to, but is sometimes syntactically convenient.

## Member Function Documentation

## ◆ skip_to()

void Xapian::PostingIterator::skip_to | ( | Xapian::docid | did | ) |

Advance the iterator to document did.

Parameters

  did | The document id to advance to. If this document id isn't in the stream being iterated, then the iterator is moved to the next document id after it which is.
