| virtual code::PolygonShapeType::~PolygonShapeType | ( | ) | [inline, virtual] |
| virtual void code::PolygonShapeType::createNetworkFormat | ( | OutputStream & | os | ) | const [virtual] |
Write a network representation into the stream.
The shape type is also written in and should not be written before hand. NOTE: ESRI's data are stored in Intel format. So, these createObject and getNetworkFormat functions should be invoked on an Intel-byte ordered stream.
Implements code::ShapeType.
| virtual void code::PolygonShapeType::createObject | ( | InputStream & | is | ) | throw (std::string) [virtual] |
Fill the object with the InputStream.
the first integer should be used to obtain the right ShapeType to invoke this function on. NOTE: ESRI's data are stored in Intel format. So, these createObject and getNetworkFormat functions should be invoked on an Intel-byte ordered stream.
Implements code::ShapeType.
| std::pair<size_t,size_t> code::PolygonShapeType::getRing | ( | size_t | index | ) | const |
Returns the starting index into the pts array and one past the ending index for the ith rings's end-points ( i is [0,numLines) ).
Clients should realize that polygons are closed and therefore, the two end-points ought to be connected even if the first point is not repeated in the shapefile.
For example usage, see the getLine function of PolyLineShapeType
| size_t code::PolygonShapeType::numRings | ( | ) | const [inline] |
A polygon shape type may contain many polygons.
| double code::PolygonShapeType::maxx |
| double code::PolygonShapeType::maxy |
| double code::PolygonShapeType::minx |
| double code::PolygonShapeType::miny |
| std::vector<int> code::PolygonShapeType::parts |
A polygon shape type is comprised of shapes called "rings".
The parts array provides an index to the pts array. This index is the starting point for this part.
| std::vector<PointShapeType> code::PolygonShapeType::pts |
ESRI_Shape code::ShapeType::type [inherited] |
ESRI's types .
.. 0 is Null, 1 is Point, etc.
