All Implemented Interfaces:

Fecundity

public final class Fecundity_Saturated
extends Fecundity_

Lifespan: permanent. Default implementation of Fecundity. Fecundity is defined according to population saturation. See the saturation thresholds: $DefaultSaturationThresholds. TODO extend this type with Fecundity_RK which conforms to the RK selection theory model.

Field Detail

$DefaultSaturationThresholds

public static final double[] $DefaultSaturationThresholds

If less than 30% saturated, then fecundity = 4; else if less than 75% saturated, then fecundity = 3; else if less than 100% saturated, then fecundity = 2; else if less than 200% saturated, then fecundity = 1; else fecundity = 0;

Constructor Detail

Fecundity_Saturated

public Fecundity_Saturated()

Constructor using default saturation thresholds, viz. $DefaultSaturationThresholds.

Fecundity_Saturated

public Fecundity_Saturated(double[] saturationThresholds)

Constructor using default saturation thresholds, viz. $DefaultSaturationThresholds.

Parameters:

saturationThresholds - This is the array of saturation thresholds for calculating fecundity. The number of possible non-zero fecundity values which may result is equal to the number of thresholds in the array. The thresholds must be ordered from highest saturation to lowest saturation. A saturation value which is higher than the 0th element will result in a zero fecundity.

Method Detail

getFecundity

public int getFecundity(Colony colony)

Get the fecundity for a population whose saturation is given by saturation. The fecundity is determined by a lookup table of thresholds which may be set via _SaturationThresholds and which defaults to $DefaultSaturationThresholds.

Parameters:

colony - the colony to which the progeny will be born.

Returns:

a number greater than 0

getFecundity

public int getFecundity(double saturation)

TODO reduce visibility to default.

Parameters:

saturation -

Returns:

a number greater than 0

setSaturationThresholds

public void setSaturationThresholds(double[] thresholds)

Typically set by bean properties (i.e. reflection, dependency injection).

Parameters:

thresholds -

getSaturationThresholds

protected double[] getSaturationThresholds()

TEST

Returns:

the array of saturation thresholds as set by setSaturationThresholds(double[]).
