Member Function Documentation

clear()

template<typename TId , typename TValue >

virtual void osmium::index::multimap::Multimap< TId, TValue >::clear ( )

pure virtual

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

Implemented in osmium::index::multimap::Hybrid< TId, TValue >, and osmium::index::multimap::SparseMemMultimap< TId, TValue >.

dump_as_list()

template<typename TId , typename TValue >

virtual void osmium::index::multimap::Multimap< TId, TValue >::dump_as_list ( const int  )

inlinevirtual

Reimplemented in osmium::index::multimap::Hybrid< TId, TValue >, and osmium::index::multimap::SparseMemMultimap< TId, TValue >.

operator=() [1/2]

template<typename TId , typename TValue >

Multimap & osmium::index::multimap::Multimap< TId, TValue >::operator= ( const Multimap< TId, TValue > &  )

delete

operator=() [2/2]

template<typename TId , typename TValue >

Multimap & osmium::index::multimap::Multimap< TId, TValue >::operator= ( Multimap< TId, TValue > &&  )

protecteddefaultnoexcept

set()

template<typename TId , typename TValue >

virtual void osmium::index::multimap::Multimap< TId, TValue >::set ( const TId  id, const TValue  value  )

pure virtual

Set the field with id to value.

Implemented in osmium::index::multimap::Hybrid< TId, TValue >, and osmium::index::multimap::SparseMemMultimap< TId, TValue >.

size()

template<typename TId , typename TValue >

virtual size_t osmium::index::multimap::Multimap< TId, TValue >::size ( ) const

pure virtual

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.

Implemented in osmium::index::multimap::Hybrid< TId, TValue >, and osmium::index::multimap::SparseMemMultimap< TId, TValue >.

sort()

template<typename TId , typename TValue >

virtual void osmium::index::multimap::Multimap< TId, TValue >::sort ( )

inlinevirtual

Sort data in map. Call this after writing all data and before reading. Not all implementations need this.

Reimplemented in osmium::index::multimap::Hybrid< TId, TValue >.

used_memory()

template<typename TId , typename TValue >

virtual size_t osmium::index::multimap::Multimap< TId, TValue >::used_memory ( ) const

pure virtual

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.

Implemented in osmium::index::multimap::Hybrid< TId, TValue >, and osmium::index::multimap::SparseMemMultimap< TId, TValue >.
