IlvMIFReader (Rogue Wave JViews 9.2 API)

java.lang.Object
- ilog.views.maps.format.midmif.IlvMIFReader

All Implemented Interfaces:

IlvMapFeatureIterator
```
public class IlvMIFReader
extends Object
implements IlvMapFeatureIterator
```
The class IlvMIFReader reads geometries from a MapInfo® Interchange file.
The .mif file of a MID/MIF file contains the attribute field definition, the positioning information, the geometries and rendering parameters of a MapInfo® Interchange file.
This reader implements all geometries from MID/MIF; The rendering parameters are attached to the read map features, as properties. The default renderer returned by this feature iterator, IlvMIFFeatureRenderer can take advantage of these properties to perform the proper rendering.

Since:

JViews 5.0
