Interface DblBuffer2d

All Known Subinterfaces:

Ca2d, ConwayLife2d, Diffuse2d

All Known Implementing Classes:

DblBuffer2dImpl

public interface DblBuffer2d

extends Discrete2d, Discrete2dS

A double buffered space.. DblBuffer2d augments Discrete2d to provide a form of double buffered space. 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.

Method Summary

java.lang.Object	putObject$atX$Y(java.lang.Object anObject, int x, int y)
java.lang.Object	putValue$atX$Y(int v, int x, int y) Overridden so writes happen to newLattice.
java.lang.Object	updateLattice() Copy newLattice to lattice, in effect updating the lattice.

updateLattice

public java.lang.Object updateLattice()

Copy newLattice to lattice, in effect updating the lattice.

putObject$atX$Y
