FeatureWriterFeatureWriters will need to allow all FeatureSources of the same typeName to issue a
FeatureEvent event of type FeatureEvent.FEATURES_REMOVED when this method is
called.
If this FeatureWriter is opperating against a Transaction FEATURES_REMOVED events should only be sent to FeatureSources operating on the same Transaction. When Transaction commit() is called other FeatureSources will be informed of the modifications.
When the current Feature has been provided as new content, this method "cancels" the add opperation (and notification needed).

FeatureWriterFeautreWriters will need to allow FeatureSources of the same typeName to issue a FeatureEvent:
false.
true and the resulting Feature has indeed been modified.
If this FeatureWriter is opperating against a Transaction the FEATURES_MODIFIED or FEATURES_ADDED events should only be sent to FeatureSources opperating on the same Transaction. When Transaction commit() is called other FeatureSources will be informed of the modifications.
If you have not called write() when you call hasNext() or next(), no modification will occur().
