Class SeriesTransition

java.lang.Object

com.codename1.charts.transitions.SeriesTransition

All Implemented Interfaces:

Animation

Direct Known Subclasses:

XYMultiSeriesTransition, XYSeriesTransition, XYValueSeriesTransition

public abstract class SeriesTransition
extends Object
implements Animation

A base class for series transitions of ChartComponent. This should be overridden by concrete classes that implement the update(int) method to update the chart's model and renderer appropriately. This class can serve as a buffer for changes to the model so that they don't affect the ChartComponent immediately. Changes can either be eased in using animateChart() or updated in one shot using updateChart().

Method Summary

Modifier and Type	Method and Description
boolean	animate() Allows the animation to reduce "repaint" calls when it returns false.
void	animateChart() Applies all pending changes to the chart model and renderer using the current animation settings.
protected void	cleanup() Cleans up any settings in the transition.
ChartComponent	getChart() Gets the ChartComponent that is the subject of the transition.
int	getDuration() Gets the duration of the transition.
int	getEasing() Gets the type of easing used in the transition.
protected void	initTransition() Initializes the transition for another iteration.
void	paint(Graphics g) Draws the animation, within a component the standard paint method would be invoked since it bares the exact same signature.
void	setChart(ChartComponent chart) Sets the ChartComponent that is the subject of the transition.
void	setDuration(int duration) Sets the duration of the transition in milliseconds.
void	setEasing(int easing) Sets the type of easing used in the transition.
protected abstract void	update(int progress) Updates the renderer and model at the specified progress position of the animation.
void	updateChart() Applies all pending changes to the chart model and renderer and repaints the chart.

Method Detail

initTransition

protected void initTransition()

Initializes the transition for another iteration. This can be overridden by subclasses to provide their own initialization. This method will be called just prior to the transition taking place. IMPORTANT: Subclasses must make sure to call super.initTransition() so that the animation will be initialized properly.

cleanup

protected void cleanup()

Cleans up any settings in the transition. Called after a transition is complete. This is meant to be overridden by subclasses.

update

protected abstract void update(int progress)

Updates the renderer and model at the specified progress position of the animation. Meant to be overridden by subclasses.

Parameters:

progress - The progress of the animation (between 0 and 100).

animate

public boolean animate()

Description copied from interface: Animation

Allows the animation to reduce "repaint" calls when it returns false. It is called once for every frame. Frames are defined by the Display class.

Specified by:

animate in interface Animation

Returns:

true if a repaint is desired or false if no repaint is necessary

paint

public void paint(Graphics g)

Description copied from interface: Animation

Draws the animation, within a component the standard paint method would be invoked since it bares the exact same signature.

Specified by:

paint in interface Animation

Parameters:

g - graphics context

getChart

public ChartComponent getChart()

Gets the ChartComponent that is the subject of the transition.

Returns:

the chart

setChart

public void setChart(ChartComponent chart)

Sets the ChartComponent that is the subject of the transition.

Parameters:

chart - the chart to set

getDuration

public int getDuration()

Gets the duration of the transition. (in milliseconds)

Returns:

the duration

setDuration

public void setDuration(int duration)

Sets the duration of the transition in milliseconds.

Parameters:

duration - the duration to set

getEasing

public int getEasing()

Gets the type of easing used in the transition. Should be one of EASING_LINEAR, EASING_IN, EASING_OUT, or EASING_IN_OUT.

Returns:

the easing

setEasing

public void setEasing(int easing)

Sets the type of easing used in the transition. Should be one of EASING_LINEAR, EASING_IN, EASING_OUT, or EASING_IN_OUT.

Parameters:

easing - the easing to set

animateChart

public void animateChart()

Applies all pending changes to the chart model and renderer using the current animation settings.

updateChart

public void updateChart()

Applies all pending changes to the chart model and renderer and repaints the chart. This is basically like calling animateChart() with a duration of 0.
