.SH NAME
Search::Xapian::ValueIterator \- Iterate over value slots in a document.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This object represents a stream of document values. It overloads \f(CW\*(C`++\*(C'\fR for
advancing the iterator, or you can explicitly call the \f(CW\*(C`inc\*(C'\fR method.
This class also overloads \f(CW\*(C`eq\*(C'\fR, \f(CW\*(C`ne\*(C'\fR, \f(CW\*(C`==\*(C'\fR, \f(CW\*(C`!=\*(C'\fR, and \f(CW""\fR
(stringification).
.SH METHODS
.IX Header "METHODS"
.IP new 4
.IX Item "new"
Constructor. Defaults to a uninitialized iterator.
.IP clone 4
.IX Item "clone"
.PD 0
.IP inc 4
.IX Item "inc"
.PD
Advance the iterator by one. (Called implictly by \f(CW\*(C`++\*(C'\fR overloading )
.IP get_valueno 4
.IX Item "get_valueno"
Return the number of the value slot at the current position.
.IP get_value 4
.IX Item "get_value"
Return the string in the value slot at current position.  Also overloaded as
the \f(CW""\fR operator.
.IP get_description 4
.IX Item "get_description"
Returns a string describing this object.
.IP "equal <valueiterator>" 4
.IX Item "equal <valueiterator>"
Checks if a valueiterator is the same as this valueiterator. Also overloaded as
the \f(CW\*(C`eq\*(C'\fR and \f(CW\*(C`!=\*(C'\fR operators.
.IP "nequal <valueiterator>" 4
.IX Item "nequal <valueiterator>"
Checks if a valueiterator is different from this valueiterator. Also overloaded
as the \f(CW\*(C`ne\*(C'\fR and \f(CW\*(C`!=\*(C'\fR operators.
