Member Function Documentation

bool tntdb::Result::const_iterator::operator!= ( const const_iterator &  it ) const

inline

Returns true, if the passed iterator points to different rows.

The iterators should point to the same resultset. This is not checked. Only the offsets are considered.

const_reference tntdb::Result::const_iterator::operator* ( ) const

inline

returns a reference to the current Row-object.

const_iterator tntdb::Result::const_iterator::operator+ ( difference_type  n ) const

inline

Returns a iterator, which points n elements further.

const_iterator& tntdb::Result::const_iterator::operator++ ( )

inline

Advances the iterator to the next element and returns the iterator to that element.

const_iterator tntdb::Result::const_iterator::operator++ ( int  )

inline

Advances the iterator to the next element and returns the previous iterator.

const_iterator& tntdb::Result::const_iterator::operator+= ( difference_type  n )

inline

Advances the iterator n elements and returns the iterator to that element.

const_iterator tntdb::Result::const_iterator::operator- ( difference_type  n ) const

inline

Returns a iterator, which points n elements back.

difference_type tntdb::Result::const_iterator::operator- ( const const_iterator &  it ) const

inline

Returns the distance between 2 iterators.

The iterators should point to the same resultset. This is not checked. Only the offsets are used.

const_iterator tntdb::Result::const_iterator::operator-- ( )

inline

Moves the iterator to the previous element and returns the iterator to that element.

const_iterator tntdb::Result::const_iterator::operator-- ( int  )

inline

Moves the iterator to the previous element and returns the previous iterator.

const_iterator& tntdb::Result::const_iterator::operator-= ( difference_type  n )

inline

Moves the iterator n elements back and returns the iterator to that element.

const_pointer tntdb::Result::const_iterator::operator-> ( ) const

inline

returns a pointer to the current Row-object.

bool tntdb::Result::const_iterator::operator== ( const const_iterator &  it ) const

inline

Returns true, if the passed iterator points to the same row.

The iterators should point to the same resultset. This is not checked. Only the offsets are considered.
