All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

BlockLattice1D, BlockLattice2D, BlockLattice3D

public abstract class BlockLattice

extends Lattice

implements java.io.Serializable

Base class for all block lattices. This group of classes implements Block CA's lattices. BlockLattice implements initialization, definition of blocks access to the States, a transition function and a reverse transition function.

Constructor Summary

BlockLattice(java.lang.Class state, de.tubs.cs.sc.casim.LatticeDefinition definition)
Constructor Base class for all block lattices only calls Lattice constructor an initializes everything to zero.

Method Summary

protected void	backup() does nothing, because Block CA's don't need any backup of cells and store only one state array
void	defineNeighborsArbitrary(int[][] indexes) neighborhoods are not allowed for Block CA's it's only for the Lattice interface.
protected void	initBlock() initializes all block specific arrays and dimensions of blocks.
protected void	reset() Base class reset only resets blockNo.
protected void	reversetransition() base class reversetransition of Block CA decreases blockCounter and swaps back to blocks length if all blocks are rounded.
protected void	transition() base class transition of Block CA increases blockCounter and swaps back to zero if all blocks are rounded.

Constructor Detail

BlockLattice

public BlockLattice(java.lang.Class state,
                    de.tubs.cs.sc.casim.LatticeDefinition definition)
             throws CAException

Constructor Base class for all block lattices only calls Lattice constructor an initializes everything to zero. State Array and Blocks will be created in subclass constructors.

Method Detail

initBlock

protected void initBlock()
                  throws CAException

initializes all block specific arrays and dimensions of blocks. Base class implementation does everything and is used by subclasses constructors to init their blocks. The dimension of all blocks are checked and stored in blockDims.

CAException

backup

protected void backup()

does nothing, because Block CA's don't need any backup of cells and store only one state array

Specified by:

backup in class Lattice

See Also:

Cell.backup(), State.copy(de.tubs.cs.sc.casim.State), BoundaryHandler.readyForBackup(int)

reset

protected void reset()
              throws CAException

Base class reset only resets blockNo. Subclasses should call BlockLattice.reset in their overridden reset.

Specified by:

reset in class Lattice

CAException

transition

protected void transition()

base class transition of Block CA increases blockCounter and swaps back to zero if all blocks are rounded. Subclasses do the real transition.

Specified by:

transition in class Lattice

See Also:

Cell.transition(), State.transition(de.tubs.cs.sc.casim.Cell), BoundaryHandler.readyForTransition(int)

reversetransition

protected void reversetransition()

base class reversetransition of Block CA decreases blockCounter and swaps back to blocks length if all blocks are rounded. Subclasses do the real reversetransition.

Specified by:

reversetransition in class Lattice

See Also:

BlockState.reversetransition(de.tubs.cs.sc.casim.BlockState[])

defineNeighborsArbitrary

public void defineNeighborsArbitrary(int[][] indexes)

neighborhoods are not allowed for Block CA's it's only for the Lattice interface.

Specified by:

defineNeighborsArbitrary in class Lattice
