Method Detail

getAllOrganisms

public DigitalOrganismIterator getAllOrganisms()

Description copied from interface: LifeSpace

This method provides all the organisms of the lifespace. This feature is needed when making the update. The order of the organisms in the iterator is arbitrary but it must remain the same all the time for one particular implementation. (Should return always a new iterator.)

Specified by:

getAllOrganisms in interface LifeSpace

getNeighbours

public DigitalOrganismIterator getNeighbours(DigitalOrganism org)

Description copied from interface: LifeSpace

This method gives the neighbours of an organism. This is needed when an organism interact with its neighbourhood. The order is arbitrary. (It may return always one instance of iterator. For performance reasons.)

Specified by:

getNeighbours in interface LifeSpace

getOrganismRandomly

public DigitalOrganism getOrganismRandomly()

Description copied from interface: LifeSpace

Gives an organism randomly from the entire 'soup'. It's needed for point mutations for example. The distribution of the hits should be uniform.

Specified by:

getOrganismRandomly in interface LifeSpace

injectGenome

public void injectGenome(GeneticCodeTape ct)

Description copied from interface: LifeSpace

Inserts a genome into the soup. The position is implementation dependent.

Specified by:

injectGenome in interface LifeSpace

getSize

public int getSize()

Description copied from interface: LifeSpace

Gives the capacity (the number of cells) of the lifespace.

Specified by:

getSize in interface LifeSpace

getRegion

public DigitalOrganismIterator getRegion(double percent)

Description copied from interface: LifeSpace

Returns organisms from a connected local territory in the lifespace. (Should return always a new iterator.)

Specified by:

getRegion in interface LifeSpace

Following copied from interface: physis.core.lifespace.LifeSpace

Parameters:

percentage - The percentage of organisms to be returned.

getSomeOrganisms

public DigitalOrganismIterator getSomeOrganisms(double precent)

Description copied from interface: LifeSpace

Returns some organisms. The organisms should be distributed uniformly in the whole lifespace. (Should return always a new iterator.)

Specified by:

getSomeOrganisms in interface LifeSpace

Following copied from interface: physis.core.lifespace.LifeSpace

Parameters:

percentage - The percentage of organisms to be returned.
