Method Detail

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

Overrides:

writeAppropriateFormat in class BasicPopulation

setUnityMinutes

public void setUnityMinutes(double minutes)

writeGeotiff

public void writeGeotiff(String fileName,
                         ResultSet results)

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

Overrides:

createIndividuals in class BasicPopulation

createIndividuals0

protected void createIndividuals0()

Shared internal createIndividuals method allowing synthetic subclass to reuse projection code
