If you do not call one of these two methods before calling hasNext(), or next() for that matter, the feature will be left unmodified. </li> <li> This API allows modification, and Filter based modification to be written. Please see AbstractDataStore for examples of implementing common opperations using this API. </li> <li> In order to add new Features, FeatureWriters capable of accepting new content allow next() to be called when hasNext() is <code>false</code> to allow new feature creation. These changes </li> </ul> <p> 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. </p><P><P><DL><DT><B>Author:</B></DT> <DD>Ian Schneider, Jody Garnett, Refractions Research</DD><DT><B>Module:</B></DT><DD><CODE><B>module/api</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-api/"><CODE>gt2-api.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/api/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/api/src/org/geotools/data/FeatureWriter.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#close()">close</A></B>()</CODE><BR> Release the underlying resources.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/geotools/feature/FeatureType.html" title="interface in org.geotools.feature">FeatureType</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#getFeatureType()">getFeatureType</A></B>()</CODE><BR> FeatureType this reader has been configured to create.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#hasNext()">hasNext</A></B>()</CODE><BR> Query whether this FeatureWriter has another Feature. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/geotools/feature/Feature.html" title="interface in org.geotools.feature">Feature</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#next()">next</A></B>()</CODE><BR> Reads a Feature from the underlying AttributeReader. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#remove()">remove</A></B>()</CODE><BR> Removes current Feature, must be called before hasNext. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureWriter.html#write()">write</A></B>()</CODE><BR> Wrties the current Feature, must be called before hasNext. </TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A>⌨️ 快捷键说明
