Parses EWKB strings and notifies of events (such as the beginning of the definition of geometry, the value of the SRID…) the factory passed as argument to the constructor.
factory = GeometryFactory::new ewkb_parser = EWKBParser::new(factory) ewkb_parser.parse(<EWKB String>) geometry = @factory.geometry
You can also use directly the static method Geometry.from_ewkb
# File lib/geo_ruby/simple_features/ewkb_parser.rb, line 28 def initialize(factory) @factory = factory @parse_options ={ 1 => method(:parse_point), 2 => method(:parse_line_string), 3 => method(:parse_polygon), 4 => method(:parse_multi_point), 5 => method(:parse_multi_line_string), 6 => method(:parse_multi_polygon), 7 => method(:parse_geometry_collection) } end
Parses the ewkb string passed as argument and notifies the factory of events
