public abstract class PhysisVirtualMachine

extends VirtualMachine

This is the base class for all virtualmachines which are implemented in Physis. This class should contain some "biological" fields and operations.

Field Summary

protected GeneticCodeTape	alien This is another codetape for alien genomes.
protected DigitalOrganism	bearer It's a backreference to the bearer digtal organism.
protected static short	blank The blank instruction.
protected int	counter counts the instructions between creating childs
protected int	gestation_time Time (in executed instructions) needed to create a child.
protected static int	GESTATION_TIME_INVALID This value shows that the VM hasn't executed a succesfull divide operation yet.
protected GeneticCodeTape	tape This codetape contains the organism's genetic code.

Constructor Summary

PhysisVirtualMachine()

Method Summary

DigitalOrganism	getBearer() Returns the bearer organism.
int	getEffectiveLength() Gives the number of copied or executed instructions.
abstract Genome	getGenome() Returns the genetic information.
abstract int	getGenomeSize() Returns the size of the genome.
int	getGestationTime() Gives the number of instructions that was needed last time to yield a new organism.
void	loadCodeTape(GeneticCodeTape ct) Loads the codetape into the VM.
abstract void	restart() This should be called after successfull proliferation.
void	setBearer(DigitalOrganism bearer_) Sets the bearer organism of the VM.

Field Detail

blank

protected static final short blank

The blank instruction. It's implicitly part of all instructionsets.

tape

protected GeneticCodeTape tape

This codetape contains the organism's genetic code.

alien

protected GeneticCodeTape alien

This is another codetape for alien genomes. (for parasitism)

bearer

protected DigitalOrganism bearer

It's a backreference to the bearer digtal organism. It's useful when generating an event and there's a need to know the digital organism. The same with environment interactions and parasitism or facing change.

GESTATION_TIME_INVALID

protected static final int GESTATION_TIME_INVALID

This value shows that the VM hasn't executed a succesfull divide operation yet.

gestation_time

protected int gestation_time

Time (in executed instructions) needed to create a child. (Actually it's the last time when birth happened.)

counter

protected int counter

counts the instructions between creating childs

Constructor Detail

PhysisVirtualMachine

public PhysisVirtualMachine()

Method Detail

getGestationTime

public int getGestationTime()

Gives the number of instructions that was needed last time to yield a new organism. If the organism hasn't spawned yet, then it returns the number of executed instructions. This way the unfertile organisms are filtered out, but the first time after birth they have good chance (low gestation time

getGenome

public abstract Genome getGenome()

Returns the genetic information.

getGenomeSize

public abstract int getGenomeSize()

Returns the size of the genome.

getEffectiveLength

public int getEffectiveLength()

Gives the number of copied or executed instructions. (It grabs it from the CodeTape.)

restart

public abstract void restart()

This should be called after successfull proliferation. (it doesn't change the gestation_time to invalid)

loadCodeTape

public void loadCodeTape(GeneticCodeTape ct)

Loads the codetape into the VM.

setBearer

public void setBearer(DigitalOrganism bearer_)

Sets the bearer organism of the VM.

getBearer

public DigitalOrganism getBearer()

Returns the bearer organism.
