Graphs are generated by supplying the generator with objects of type LineSegment via the add(Object) method. <BR> <BR> For each line segment added, an edge in the graph is created. The builder records the end coordinates of each line added, and maintains a map of coordinates to nodes, creating nodes when neccessary.<BR> <BR> Edges created by the generator are of type OptBasicEdge.<BR> Nodes created by the generator are of type OptXYNode. <BR> <BR> Since building optimized graphs requires knowing the degree of nodes before creating them, the physical construction of the graph is delayed until a call to generate() is made. No component is created with a call to add(Object), only information about the object is recorded.<P><P><DL><DT><B>Author:</B></DT> <DD>Justin Deoliveira, Refractions Research Inc, jdeolive@refractions.net</DD><DT><B>See Also:</B><DD><A HREF="../../../../../org/geotools/graph/structure/opt/OptEdge.html" title="class in org.geotools.graph.structure.opt"><CODE>OptEdge</CODE></A>, <A HREF="../../../../../org/geotools/graph/structure/line/OptXYNode.html" title="class in org.geotools.graph.structure.line"><CODE>OptXYNode</CODE></A><DT><B>Module:</B></DT><DD><CODE><B>ext/graph</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-graph/"><CODE>gt2-graph.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/graph/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/ext/graph/src/org/geotools/graph/build/line/OptLineGraphGenerator.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../../org/geotools/graph/build/line/OptLineGraphGenerator.html#OptLineGraphGenerator()">OptLineGraphGenerator</A></B>()</CODE><BR> Constructs a new OptLineGraphGenerator.</TD></TR></TABLE> <!-- ========== 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/graph/structure/Graphable.html" title="interface in org.geotools.graph.structure">Graphable</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/geotools/graph/build/line/OptLineGraphGenerator.html#add(java.lang.Object)">add</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A> obj)</CODE><BR> Adds a line to the graph. </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/graph/build/line/OptLineGraphGenerator.html#generate()">generate</A></B>()</CODE><BR> Performs the actual generation of the graph.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../../../../org/geotools/graph/structure/Edge.html" title="interface in org.geotools.graph.structure">Edge</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/geotools/graph/build/line/OptLineGraphGenerator.html#generateEdge(com.vividsolutions.jts.geom.LineSegment)">generateEdge</A></B>(<A HREF="http://www.jump-project.org/docs/jts/1.7/api/com/vividsolutions/jts/geom/LineSegment.html" title="class or interface in com.vividsolutions.jts.geom">LineSegment</A> line)</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/geotools/graph/build/line/OptLineGraphGenerator.html#generateEdges()">generateEdges</A></B>()</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1">⌨️ 快捷键说明
