string ValueStreamDocument::get_value

(

Xapian::valueno

slot

)

const [inline]

Get value by value number.

Values are quickly accessible fields, for use during the match operation. Each document may have a set of values, each of which having a different value number. Duplicate values with the same value number are not supported in a single document.

Value numbers are any integer >= 0, but particular database backends may impose a more restrictive range than that.

Parameters:

slot

The value number requested.

Returns:

A string containing the specified value. If the value is not present in this document, the value's value will be a zero length string
