Basically, for a SLD, you create one of these for each of the FeatureTypeStyles inside it. LiteRenderer uses this to do the actual renderering. It contains: a. a BufferedImage so lite knows where to do the drawing b. a list of rules (minimal # -- ie. remove the ones that dont apply to this scale) c. "else" rule list To process this, you would a) foreach FEATURE b) foreach LiteFeatureTypeStyle c) <process rules and draw to the appropriate image> d) combine the images This was setup so you can "parallelize" literenderer in the simple way -- only read data once. The old implementation would re-read the data for each one FeatureTypeStyle. NOTE: a) the SLD spec says that each FeatureTypeStyle is rendered in order & independently b) If you have a request like LAYERS=a,a&STYLES=a_style1,a_styel2 then you could optimize to something like this (!!) NOTE: a) this also sets up the image -- clears it et al.<P><P><DL><DT><B>Author:</B></DT> <DD>dblasby</DD><DT><B>Module:</B></DT><DD><CODE><B>module/render</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-render/"><CODE>gt2-render.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/render/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/render/src/org/geotools/renderer/lite/LiteFeatureTypeStyle.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field 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/styling/Rule.html" title="interface in org.geotools.styling">Rule</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/renderer/lite/LiteFeatureTypeStyle.html#elseRules">elseRules</A></B></CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/Graphics2D.html" title="class or interface in java.awt">Graphics2D</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/renderer/lite/LiteFeatureTypeStyle.html#graphics">graphics</A></B></CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/BufferedImage.html" title="class or interface in java.awt.image">BufferedImage</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/renderer/lite/LiteFeatureTypeStyle.html#myImage">myImage</A></B></CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../../org/geotools/styling/Rule.html" title="interface in org.geotools.styling">Rule</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/geotools/renderer/lite/LiteFeatureTypeStyle.html#ruleList">ruleList</A></B></CODE><BR> </TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY="">⌨️ 快捷键说明
