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.
