Method Detail

addIndividual

public void addIndividual(Individual individual)

Specified by:

addIndividual in interface Population

iterator

public Iterator<Individual> iterator()

Specified by:

iterator in interface Iterable<Individual>

clearIndividuals

public void clearIndividuals(List<Individual> individuals)

Specified by:

clearIndividuals in interface Population

createIndividuals

public void createIndividuals()

Description copied from interface: Population

Subclass-specific method to load the individuals from a file or create them based on other properties. This method should fill in all fields of each individual except the sample, since sampling will be carried out after the filter chain is applied.

Specified by:

createIndividuals in interface Population

size

public int size()

Specified by:

size in interface Population

Returns:

the number of individuals in this population.

writeCsv

protected void writeCsv(String outFileName,
                        ResultSet results)

writeAppropriateFormat

public void writeAppropriateFormat(String outFileName,
                                   ResultSet results)

Description copied from interface: Population

Save the output data in this population to a file, using a format that is appropriate for the specific class of population. For example, a population loaded from an image file or generated on a regular grid will be saved as a Geotiff raster. A population of points that are not known to be aligned on a regular grid in some CRS will be saved as a CSV file.

Specified by:

writeAppropriateFormat in interface Population

setup

public void setup()

Description copied from interface: Population

Prepare the population for use. This includes loading or generating the individuals, filtering them, but not sampling (linking them into the graph) because origin populations do not need to be permanently linked.

Specified by:

setup in interface Population
