Examples of FeatureWriter

org.geotools.data.FeatureWriter
Provides the ability to write Features information.
Capabilities:
- Similar API to FeatureReader
- After aquiring a feature using next() you may call remove() or after modification write(). If you do not call one of these two methods before calling hasNext(), or next() for that matter, the feature will be left unmodified.
- This API allows modification, and Filter based modification to be written. Please see AbstractDataStore for examples of implementing common opperations using this API.
- In order to add new Features, FeatureWriters capable of accepting new content allow next() to be called when hasNext() is false to allow new feature creation. These changes
One thing that is really nice about the approach to adding content is that the generation of FID is not left in the users control.
