Detailed Description

template<typename TAssembler>
class osmium::area::MultipolygonCollector< 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 class osmium::relations::Collector.

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.

Deprecated:

Use MultipolygonManager instead.
