/**
|
|
There are two possibilities how to use this class:
|
|
1. static call to QgsVectorFileWriter::writeAsShapefile(...) which saves the whole vector layer
|
|
2. create an instance of the class and issue calls to addFeature(...)
|
|
|
|
Currently supports only writing to shapefiles, but shouldn't be a problem to add capability
|
|
to support other OGR-writable formats.
