Detailed Description

template<typename TId, typename TValue>
class osmium::index::map::Dummy< TId, TValue >

Pseudo map. Use this class if you don't need a map, but you need an object that behaves like one.

Member Function Documentation

clear()

template<typename TId , typename TValue >

void osmium::index::map::Dummy< TId, TValue >::clear ( )

inlinefinalvirtual

Clear memory used for this storage. After this you can not use the storage container any more.

Implements osmium::index::map::Map< TId, TValue >.

get()

template<typename TId , typename TValue >

TValue osmium::index::map::Dummy< TId, TValue >::get ( const TId  id ) const

inlinefinalvirtual

Retrieve value by id.

Parameters

id	The id to look for.

Returns

Value.

Exceptions

osmium::not_found

if the id could not be found.

Implements osmium::index::map::Map< TId, TValue >.

get_noexcept()

template<typename TId , typename TValue >

TValue osmium::index::map::Dummy< TId, TValue >::get_noexcept ( const  id ) const

inlinefinalvirtualnoexcept

Retrieve value by id.

Parameters

id	The id to look for.

Returns

Value or, if not found, the empty value as defined by osmium::index::empty_value<TValue>() which is usually the default constructed value of type TValue.

Implements osmium::index::map::Map< TId, TValue >.

template<typename TId , typename TValue >

Dummy & osmium::index::map::Dummy< TId, TValue >::operator= ( Dummy< TId, TValue > &&  )

defaultnoexcept

set()

template<typename TId , typename TValue >

void osmium::index::map::Dummy< TId, TValue >::set ( const  id, const  value  )

inlinefinalvirtual

Set the field with id to value.

Implements osmium::index::map::Map< TId, TValue >.

size()

template<typename TId , typename TValue >

size_t osmium::index::map::Dummy< TId, TValue >::size ( ) const

inlinefinalvirtual

Get the approximate number of items in the storage. The storage might allocate memory in blocks, so this size might not be accurate. You can not use this to find out how much memory the storage uses. Use used_memory() for that.

Implements osmium::index::map::Map< TId, TValue >.

used_memory()

template<typename TId , typename TValue >

size_t osmium::index::map::Dummy< TId, TValue >::used_memory ( ) const

inlinefinalvirtual

Get the memory used for this storage in bytes. Note that this is not necessarily entirely accurate but an approximation. For storage classes that store the data in memory, this is the main memory used, for storage classes storing data on disk this is the memory used on disk.

Implements osmium::index::map::Map< TId, TValue >.
