## Detailed Description

Class representing an ordered set of expand terms (an ESet).

This set represents the results of an expand operation, which is performed by Xapian::Enquire::get_eset().

## Constructor & Destructor Documentation

Xapian::ESet::ESet | ( |  | ) |

Construct an empty ESet.

Xapian::ESet::~ESet | ( |  | ) |

Destructor.

Xapian::ESet::ESet | ( | const ESet & | other | ) |

Copying is allowed (and is cheap).

## Member Function Documentation

void Xapian::ESet::operator= | ( | const ESet & | other | ) |

Assignment is allowed (and is cheap).

Xapian::termcount Xapian::ESet::get_ebound | ( |  | ) | const

A lower bound on the number of terms which are in the full set of results of the expand.

This will be greater than or equal to size()

Xapian::termcount Xapian::ESet::size | ( |  | ) | const

The number of terms in this E-Set.

Xapian::termcount Xapian::ESet::max_size | ( |  | ) | const`[inline]`

Required to allow use as an STL container.

bool Xapian::ESet::empty | ( |  | ) | const

Test if this E-Set is empty.

void Xapian::ESet::swap | ( | ESet & | other | ) |

Swap the E-Set we point to with another.

ESetIterator Xapian::ESet::begin | ( |  | ) | const

Iterator for the terms in this E-Set.

ESetIterator Xapian::ESet::end | ( |  | ) | const

End iterator corresponding to begin().

ESetIterator Xapian::ESet::back | ( |  | ) | const

Iterator pointing to the last element of this E-Set.

ESetIterator Xapian::ESet::operator[] | ( | Xapian::termcount | i | ) | const

This returns the term at position i in this E-Set.

std::string Xapian::ESet::get_description | ( |  | ) | const

Return a string describing this object.
