| Add a term to the document, without positional information. | |

| Remove a posting of a term from the document. | |
| void | remove_term (const std::string &tname) |
| Remove a term and all postings associated with it. | |
| void | clear_terms () |
| Remove all terms (and postings) from the document. | |
| Xapian::termcount | termlist_count () const |
| The length of the termlist - i.e. | |
| TermIterator | termlist_begin () const |
| Iterator for the terms in this document. | |
| TermIterator | termlist_end () const |
| Equivalent end iterator for termlist_begin(). | |
| Xapian::termcount | values_count () const |
| Count the values in this document. | |
| ValueIterator | values_begin () const |
| Iterator for the values in this document. | |
| ValueIterator | values_end () const |
| Equivalent end iterator for values_begin(). | |
| docid | get_docid () const |
| Get the document id which is associated with this document (if any). | |
| std::string | get_description () const |
| Return a string describing this object. | |
| Xapian::Document::Document | ( | const Document & | other | ) |
Copying is allowed.
The internals are reference counted, so copying is cheap.
| Xapian::Document::Document | ( | ) |
Make a new empty Document.
| Xapian::Document::~Document | ( | ) |
Destructor.
| void Xapian::Document::operator= | ( | const Document & | other | ) |
Assignment is allowed.
The internals are reference counted, so assignment is cheap.
| std::string Xapian::Document::get_value | ( | Xapian::valueno | valueno | ) | const |
Get value by number.
Returns an empty string if no value with the given number is present in the document.
| valueno | The number of the value. |
| void Xapian::Document::add_value | ( | Xapian::valueno | valueno, | |
| const std::string & | value | |||
| ) |
Add a new value.
It will replace any existing value with the same number.
| void Xapian::Document::remove_value | ( | Xapian::valueno | valueno | ) |
Remove any value with the given number.
| void Xapian::Document::clear_values | ( | ) |
Remove all values associated with the document.
| std::string Xapian::Document::get_data | ( | ) | const |
Get data stored in the document.
This is a potentially expensive operation, and shouldn't normally be used in a match decider functor. Put data for use by match deciders in a value instead.
| void Xapian::Document::set_data | ( | const std::string & | data | ) |
Set data stored in the document.
| void Xapian::Document::add_posting | ( | const std::string & | tname, | |
| Xapian::termpos | tpos, | |||
| Xapian::termcount | wdfinc = 1 | |||
| ) |
Add an occurrence of a term at a particular position.
Multiple occurrences of the term at the same position are represented only once in the positional information, but do increase the wdf.
If the term is not already in the document, it will be added to it.
| tname | The name of the term. | |
| tpos | The position of the term. | |
| wdfinc | The increment that will be applied to the wdf for this term. |
| void Xapian::Document::add_term | ( | const std::string & | tname, | |
| Xapian::termcount | wdfinc = 1 | |||
| ) |
Add a term to the document, without positional information.
Any existing positional information for the term will be left unmodified.
| tname | The name of the term. | |
| wdfinc | The increment that will be applied to the wdf for this term. |
| void Xapian::Document::remove_posting | ( | const std::string & | tname, | |
| Xapian::termpos | tpos, | |||
| Xapian::termcount | wdfdec = 1 | |||
| ) |
Remove a posting of a term from the document.
Note that the term will still index the document even if all occurrences are removed. To remove a term from a document completely, use remove_term().
| tname | The name of the term. | |
| tpos | The position of the term. | |
| wdfdec | The decrement that will be applied to the wdf when removing this posting. The wdf will not go below the value of 0. |
| Xapian::InvalidArgumentError | will be thrown if the term is not at the position specified in the position list for this term in this document. | |
| Xapian::InvalidArgumentError | will be thrown if the term is not in the document |
| void Xapian::Document::remove_term | ( | const std::string & | tname | ) |
Remove a term and all postings associated with it.
| tname | The name of the term. |
| Xapian::InvalidArgumentError | will be thrown if the term is not in the document |
| void Xapian::Document::clear_terms | ( | ) |
Remove all terms (and postings) from the document.
| Xapian::termcount Xapian::Document::termlist_count | ( | ) | const |
The length of the termlist - i.e.
the number of different terms which index this document.
| TermIterator Xapian::Document::termlist_begin | ( | ) | const |
Iterator for the terms in this document.
| TermIterator Xapian::Document::termlist_end | ( | ) | const [inline] |
Equivalent end iterator for termlist_begin().
| Xapian::termcount Xapian::Document::values_count | ( | ) | const |
Count the values in this document.
| ValueIterator Xapian::Document::values_begin | ( | ) | const |
Iterator for the values in this document.
| ValueIterator Xapian::Document::values_end | ( | ) | const |
Equivalent end iterator for values_begin().
| docid Xapian::Document::get_docid | ( | ) | const |
Get the document id which is associated with this document (if any).
NB If multiple databases are being searched together, then this will be the document id in the individual database, not the merged database!
| std::string Xapian::Document::get_description | ( | ) | const |
Return a string describing this object.
