Implements dballe::Cursor.

enq()

template<typename Station>

void dballe::db::summary::Cursor< Station >::enq ( impl::Enq & enq ) const

overridevirtual

Implements dballe::impl::CursorSummary.

template<typename Station>

Level dballe::db::summary::Cursor< Station >::get_level ( ) const

inlineoverridevirtual

Get the level.

Implements dballe::CursorSummary.

get_station()

template<typename Station>

DBStation dballe::db::summary::Cursor< Station >::get_station ( ) const

inlineoverridevirtual

Get the whole station data in a single call.

Implements dballe::Cursor.

get_trange()

template<typename Station>

Implements dballe::CursorSummary.

has_value()

template<typename Station>

bool dballe::db::summary::Cursor< Station >::has_value ( ) const

inlineoverridevirtual

Check if the cursor points to a valid value.

Returns

true if the cursor points to a valid accessible value, false if next() has not been called yet, or if at the end of iteration (i.e. next() returned false)

Implements dballe::Cursor.

next()

template<typename Station>

bool dballe::db::summary::Cursor< Station >::next ( )

inlineoverridevirtual

Get a new item from the results of a query.

remaining()

template<typename Station>

int dballe::db::summary::Cursor< Station >::remaining ( ) const

inlineoverridevirtual

Get the number of rows still to be fetched.

Returns

The number of rows still to be queried. The value is undefined if no query has been successfully peformed yet using this cursor.
