Two lattices are maintained: lattice (the current state), and newLattice (the future state). All reads take place from lattice, all writes take place to newLattice. newLattice is copied to lattice when updateLattice is called. DblBuffer2d can be used to implement one model of concurrent action, like in Ca2ds. NOTE: be very careful if you're using low-level macro access to the world, in particular be sure that you preserve the write semantics on the newLattice.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><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="../../swarm/space/DblBuffer2dImpl.html#DblBuffer2dImpl()">DblBuffer2dImpl</A></B>()</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../swarm/space/DblBuffer2dImpl.html#DblBuffer2dImpl(swarm.defobj.Zone)">DblBuffer2dImpl</A></B>(<A HREF="../../swarm/defobj/Zone.html">Zone</A> aZone)</CODE><BR> The create: message creates a new instance of a type with default options.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../swarm/space/DblBuffer2dImpl.html#DblBuffer2dImpl(swarm.defobj.Zone, int, int)">DblBuffer2dImpl</A></B>(<A HREF="../../swarm/defobj/Zone.html">Zone</A> aZone, int x, int y)</CODE><BR> Convenience constructor for Discrete2d lattice</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="methods_implemented_from_interfaces_swarm.space.Discrete2d"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods implemented by this class for interface swarm.space.<A HREF="../../swarm/space/Discrete2d.html">Discrete2d</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/space/Discrete2d.html#copyDiscrete2d$toDiscrete2d(swarm.space.Discrete2d, swarm.space.Discrete2d)">copyDiscrete2d$toDiscrete2d</A>, <A HREF="../../swarm/space/Discrete2d.html#fastFillWithObject(java.lang.Object)">fastFillWithObject</A>, <A HREF="../../swarm/space/Discrete2d.html#fastFillWithValue(int)">fastFillWithValue</A>, <A HREF="../../swarm/space/Discrete2d.html#fillWithObject(java.lang.Object)">fillWithObject</A>, <A HREF="../../swarm/space/Discrete2d.html#fillWithValue(int)">fillWithValue</A>, <A HREF="../../swarm/space/Discrete2d.html#putObject$atX$Y(java.lang.Object, int, int)">putObject$atX$Y</A>, <A HREF="../../swarm/space/Discrete2d.html#putValue$atX$Y(int, int, int)">putValue$atX$Y</A>, <A HREF="../../swarm/space/Discrete2d.html#setDiscrete2d$toFile(swarm.space.Discrete2d, java.lang.String)">setDiscrete2d$toFile</A></CODE></TD></TR></TABLE> <A NAME="methods_implemented_from_interfaces_swarm.space.Discrete2dS"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods implemented by this class for interface swarm.space.<A HREF="../../swarm/space/Discrete2dS.html">Discrete2dS</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/space/Discrete2dS.html#setObjectFlag(boolean)">setObjectFlag</A></CODE></TD></TR></TABLE> <A NAME="methods_implemented_from_interfaces_swarm.space.DblBuffer2d"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods implemented by this class for interface swarm.space.<A HREF="../../swarm/space/DblBuffer2d.html">DblBuffer2d</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/space/DblBuffer2d.html#putObject$atX$Y(java.lang.Object, int, int)">putObject$atX$Y</A>, <A HREF="../../swarm/space/DblBuffer2d.html#putValue$atX$Y(int, int, int)">putValue$atX$Y</A>, <A HREF="../../swarm/space/DblBuffer2d.html#updateLattice()">updateLattice</A></CODE></TD></TR></TABLE> <A NAME="methods_implemented_from_interfaces_swarm.objectbase.SwarmObject"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods implemented by this class for interface swarm.objectbase.<A HREF="../../swarm/objectbase/SwarmObject.html">SwarmObject</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/objectbase/SwarmObject.html#getCompleteProbeMap()">getCompleteProbeMap</A>, <A HREF="../../swarm/objectbase/SwarmObject.html#getProbeForMessage(java.lang.String)">getProbeForMessage</A>, <A HREF="../../swarm/objectbase/SwarmObject.html#getProbeForVariable(java.lang.String)">getProbeForVariable</A>, <A HREF="../../swarm/objectbase/SwarmObject.html#getProbeMap()">getProbeMap</A></CODE></TD>⌨️ 快捷键说明
