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().

    Modifier and Type
    Method
    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.

    • SeriesTransition

      public SeriesTransition(ChartComponent chart)

    • SeriesTransition

      public SeriesTransition(ChartComponent chart, int easing)

    • SeriesTransition

      public SeriesTransition(ChartComponent chart, int easing, int duration)

  • Method Details

    • 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 com.codename1.ui.Display class.

      Returns

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

      Specified by:
      animate in interface Animation

    • 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.

      Parameters
      • g: graphics context
      Specified by:
      paint in interface Animation

    • 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.
