  +--org.artoflife.gui.population.VerticalFitnessPolicy

All Implemented Interfaces:

RecordPositionPolicy

Direct Known Subclasses:

FreeVerticalFitnessPolicy

public class VerticalFitnessPolicy

extends java.lang.Object

implements RecordPositionPolicy

A RecordPositionPolicy that positions Individuals vertically according to their Fitness (scaled to some range) and horizontally by record index with a constant individual width to fit the population's ideal size across the entire width of the parent view. The ideal size is collected from the population when this is first associated with its PopulationView in setPopulationView(PopulationView) and when the bounds changes during updateBounds() so that transient fluctuations in population size don't immediately change all IndividualRecord positioning.

Field Detail

view

protected PopulationView view

The parent PopulationView that uses this policy.

numberOfIndividuals

protected int numberOfIndividuals

Number of individuals to fit across width. This is the ideal size of population gathered during setPopulationView(PopulationView) and updateBounds().

spacer

protected int spacer

Horizontal space between individuals. Default to 2.

individualWidth

protected int individualWidth

Calculated in updateBounds().

Constructor Detail

VerticalFitnessPolicy

public VerticalFitnessPolicy(float minFitness,
                             float maxFitness)

Create with a defined min and max fitness to define the vertical scale.

Method Detail

getMaxFitness

public float getMaxFitness()

setMaxFitness

public void setMaxFitness(float maxFitness)

getMinFitness

public float getMinFitness()

setMinFitness

public void setMinFitness(float minFitness)

getSpacer

public int getSpacer()

setSpacer

public void setSpacer(int spacer)

positionNew

public void positionNew(org.artoflife.gui.population.IndividualRecord record,
                        int index)

Description copied from interface: RecordPositionPolicy

Find a position for an Individual newly added to the view at a specified index and set the IndividualRecord's state appropriately.

Specified by:

positionNew in interface RecordPositionPolicy

See Also:

org.artoflife.gui.paintable.view.RecordPositionPolicy#positionNew(IndividualRecord, int)

positionNewAt

public void positionNewAt(org.artoflife.gui.population.IndividualRecord record,
                          int index,
                          java.awt.Point location)

Description copied from interface: RecordPositionPolicy

Position a record at a certain location (if possible), altering the Individual within the passed IndividualRecord if necessary to make it fit at that location. For example, VerticalFitnessPolicy sets the Individual's Fitness to fit the Y location but ignores the X location.

Specified by:

positionNewAt in interface RecordPositionPolicy

See Also:

RecordPositionPolicy.positionNewAt(org.artoflife.gui.population.IndividualRecord, int, java.awt.Point)

positionAfterChange

public void positionAfterChange(org.artoflife.gui.population.IndividualRecord record,
                                int index)

Description copied from interface: RecordPositionPolicy

Reposition a record (at a given index within the view) whose Individual changed in some way.

Specified by:

positionAfterChange in interface RecordPositionPolicy

org.artoflife.gui.paintable.view.RecordPositionPolicy#positionAfterChange(IndividualRecord)

repositionForViewBounds

public void repositionForViewBounds(org.artoflife.gui.population.IndividualRecord record,
                                    int index,
                                    int x,

                                    int height)

Description copied from interface: RecordPositionPolicy

Reposition an IndividualRecord (at a given index within the view) so it fits in the parent view's new bounds passed in as parameters. Note that the view is still at its old size when this gets called.

Specified by:

repositionForViewBounds in interface RecordPositionPolicy
