Detailed Description

template<typename TAssembler>
class osmium::area::MultipolygonManager< TAssembler >

This class collects all data needed for creating areas from relations tagged with type=multipolygon or type=boundary. Most of its functionality is derived from the parent template class osmium::relations::RelationsManager.

The actual assembling of the areas is done by the assembler class given as template argument.

Template Parameters

TAssembler Multipolygon Assembler class.

Precondition: The Ids of all objects must be unique in the input data.

Member Typedef Documentation

◆ assembler_config_type

template<typename TAssembler >

using osmium::area::MultipolygonManager< TAssembler >::assembler_config_type = typename TAssembler::config_type

private

Constructor & Destructor Documentation

◆ MultipolygonManager()

template<typename TAssembler >

osmium::area::MultipolygonManager< TAssembler >::MultipolygonManager	(	assembler_config_type	assembler_config,
		osmium::TagsFilter	filter = `osmium::TagsFilter{true}`
	)

inlineexplicit

Construct a MultipolygonManager.

Parameters

assembler_config	The configuration that will be given to any newly constructed area assembler.
filter	An optional filter specifying what tags are needed on closed ways or multipolygon relations to build the area.

Member Function Documentation

◆ after_way()

template<typename TAssembler >

void osmium::area::MultipolygonManager< TAssembler >::after_way ( const osmium::Way & way )

inline

◆ complete_relation()

template<typename TAssembler >

void osmium::area::MultipolygonManager< TAssembler >::complete_relation ( const osmium::Relation & relation )

inline

This is called when a relation is complete, ie. all members were found in the input. It will build the area using the assembler.

◆ new_relation()

template<typename TAssembler >

bool osmium::area::MultipolygonManager< TAssembler >::new_relation ( const osmium::Relation & relation ) const

inline

We are interested in all relations tagged with type=multipolygon or type=boundary with at least one way member.

◆ stats()

template<typename TAssembler >

const area_stats & osmium::area::MultipolygonManager< TAssembler >::stats ( ) const

inlinenoexcept

Access the aggregated statistics generated by the assemblers called from the manager.
