 <p>
 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.
 </p>

 <p>
 When the current Feature has been provided as new content, this method
 "cancels" the add opperation (and notification needed).

<DD>Wrties the current Feature, must be called before hasNext.

 <p>
 FeautreWriters will need to allow FeatureSources of the same typeName to
 issue a FeatureEvent:
 </p>

 <ul>
 <li>
 FeatureEvent.FEATURES_ADDED: when next() has been called with hasNext()
 equal to <code>false</code>.
 </li>
 <li>
 FeatureEvent.FEATURES_MODIFIED: when next has been called with hasNext()
 equal to <code>true</code> and the resulting Feature has indeed been
 modified.
 </li>
 </ul>

 <p>
 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.
 </p>

 <p>
 If you have not called write() when you call hasNext() or next(), no
 modification will occur().

<DD>Inserts a feature into the database.
 
 <p>
 This method should both insert a Feature, and update its FID in case the
 FIDMapper works over database generated ids like  autoincrement fields,
 sequences, and object ids.
 </p>
 
 <p>
 Postgis needs to do this seperately.  With updates it can just override
 the geometry stuff, using a direct sql update statement, but for
 inserts it can't update a row that doesn't exist yet.

<DD>Query whether this FeatureWriter has another Feature.

 <p>
 Please note: it is more efficient to construct your FeatureWriter with a
 Filer (to skip entries you do not want), than to force the creation of
 entire Features only to skip over them.

 <p>
 FeatureWriters that support append opperations will allow calls to next,
 even when haveNext() returns <code>false</code>.
