public interface IlvMapFeatureIterator
IlvMapLoader
Modifier and Type | Method and Description |
---|---|
void |
dispose()
Releases the resources allocated by the feature iterator
(files, connections, and so on).
|
IlvCoordinateSystem |
getCoordinateSystem()
Returns the spatial reference system that describes the coordinate
system of geometric coordinates of the map features.
|
IlvFeatureRenderer |
getDefaultFeatureRenderer()
Returns a renderer that can be used to translate the map features returned
by this iterator into graphic objects.
|
IlvCoordinate |
getLowerRightCorner()
Returns the lower right corner of the rectangle containing all
the map feature of the list, or
null
if the iterator cannot provide this information. |
IlvMapFeature |
getNextFeature()
Returns the next map feature of the iterator or
null if the iteration is finished. |
IlvCoordinate |
getUpperLeftCorner()
Returns the upper left corner of the rectangle containing all
the map features of the list, or
null
if the iterator cannot provide this information. |
boolean |
isGeoreferenced()
Returns
true if the map reader can provide the
source projection of its map features. |
IlvMapFeature getNextFeature() throws IOException
null
if the iteration is finished.
The returned map feature must be considered as volatile and
can be modified by the reader during the next call to its
getNextFeature
function.IOException
