# Xapian::ESetIterator Class Reference

Iterate through terms in the ESet. More...

List of all members.

## Public Types

typedef std::bidirectional_iterator_tag | iterator_category
| Allow use as an STL iterator.
typedef std::string | value_type
| Allow use as an STL iterator.
typedef Xapian::termcount_diff | difference_type
| Allow use as an STL iterator.
typedef std::string * | pointer
| Allow use as an STL iterator.
typedef std::string & | reference
| Allow use as an STL iterator.

## Public Member Functions

| ESetIterator ()
| Create an uninitialised iterator; this cannot be used, but is convenient syntactically.
| ESetIterator (const ESetIterator &other)
| Copying is allowed (and is cheap).
void | operator= (const ESetIterator &other)
| Assignment is allowed (and is cheap).
ESetIterator & | operator++ ()
| Advance the iterator.
ESetIterator | operator++ (int)
| Advance the iterator (postfix variant).
ESetIterator & | operator-- ()
| Decrement the iterator.
ESetIterator | operator-- (int)
| Decrement the iterator (postfix variant).
const std::string & | operator* () const
| Get the term for the current position.
Xapian::weight | get_weight () const
| Get the weight of the term at the current position.
std::string | get_description () const
| Return a string describing this object.

## Friends

bool | operator== (const ESetIterator &a, const ESetIterator &b)
| Equality test for ESetIterator objects.
bool | operator!= (const ESetIterator &a, const ESetIterator &b)
| Inequality test for ESetIterator objects.

## Detailed Description

Iterate through terms in the ESet.
