parseBlockArea

public GraphEdgeIdFinder.BlockArea parseBlockArea(String blockAreaString,
                                                  EdgeFilter filter,
                                                  double useEdgeIdsUntilAreaSize)

This method reads the blockAreaString and creates a Collection of Shapes or a set of found edges if area is small enough.

Parameters:

useEdgeIdsUntilAreaSize - until the specified area (specified in m²) use the findEdgesInShape method
