It is a Query that knows enough information to be rerun. We may wish to rename this class as QueryResults. </p> <p> Differences from FeatureCollection: </p> <ul> <li> This API opperates as a source of FeatureReaders (rather than a source of iterators) </li> <li> As a Prepaired Query thise class allows other "results" to be asked against the same query. getBounds() is the most logical example, but we may be able to think of others. In Candidate "results" should all be reproduceable by streaming over the generated FeatureReader. </li> </ul> <p> Ideas: </p> <ul> <li> Chris had the idea of a collection() method that would construct a FeatureCollection (by iterating through the FeartureReader once). This would be a nice transition piece to allow us to test against existing renderers. (we could add the method in deprecated form until the Renderers adapt to the new API). </li> <li> Ian had the idea of asynchronous error handling as provided by a High-Level version of FeatureReader. This class might be the place for such work? Something similar to jdbc getWarnings()? </li> <li> The idea of forcing a CoordinateSystem is also looking for a home, this may be the place for such work (although I recomend proving a a "hint" in the Query interface). </li> </ul><P><P><DL><DT><B>Author:</B></DT> <DD>Jody Garnett, Ray Gallagher, Rob Hranac, TOPP, Chris Holmes, TOPP</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/FeatureResults.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> <A HREF="../../../org/geotools/feature/FeatureCollection.html" title="interface in org.geotools.feature">FeatureCollection</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureResults.html#collection()">collection</A></B>()</CODE><BR> <B>Deprecated.</B> <I>please consider explicitly constructing a feaure collection</I></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://www.jump-project.org/docs/jts/1.7/api/com/vividsolutions/jts/geom/Envelope.html" title="class or interface in com.vividsolutions.jts.geom">Envelope</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureResults.html#getBounds()">getBounds</A></B>()</CODE><BR> Returns the bounding box of this FeatureResults. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureResults.html#getCount()">getCount</A></B>()</CODE><BR> <B>Deprecated.</B> <I>Please use FeatureCollection.size() instead</I></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/FeatureResults.html#getSchema()">getSchema</A></B>()</CODE><BR> Returns the FeatureType of the contents of this collection. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/geotools/data/FeatureReader.html" title="interface in org.geotools.data">FeatureReader</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/FeatureResults.html#reader()">reader</A></B>()</CODE><BR> <B>Deprecated.</B> <I>please use FeatureCollections.features() to obtain a FeatureIterator</I></TD></TR></TABLE> ⌨️ 快捷键说明
