Class improv.util.Curve 

java.lang.Object
   |
   +----improv.util.Curve
public abstract class Curve
extends Object
implements Animator
The Curve class is the base class for all Improv curve objects. Perhaps the most important method in the Curve class is the eval() method, which is used to compute the value of the curve at a particular time.

Method Index

o eval(double)
This is called from the animate method and is overridden by the individual curve classes.
o getCompositeMode()
o getOffset()
o getOverlay()
o getValue(double, double)
o setCompositeMode(int)
used to set the composite mode of a curve
o setOffset(double)
Used to set a temporal offset for the curve
o setOverlay(Animator)
Used to set an overlay curve with the default composite method of "ADD"
o setOverlay(Animator, String)
Used to set an overlay curve and a composite method
o setValue(double)
o timeBased(boolean)
This is called by the various filter types to determine the current value of the filter.

Methods

o timeBased 
 public void timeBased(boolean b)
This is called by the various filter types to determine the current value of the filter. This is overriden by the EditableCurve and ParameterizedCurve classes.

o setValue 
 public void setValue(double d)
o eval 
 public abstract double eval(double x)
This is called from the animate method and is overridden by the individual curve classes.

o setOffset 
 public void setOffset(double d)
Used to set a temporal offset for the curve

o setOverlay 
 public void setOverlay(Animator anim)
Used to set an overlay curve with the default composite method of "ADD"

o setOverlay 
 public void setOverlay(Animator anim,
                        String composite)
Used to set an overlay curve and a composite method

o setCompositeMode 
 public void setCompositeMode(int i)
used to set the composite mode of a curve

o getOverlay 
 public Curve getOverlay()
Returns:
the overlay curve
o getCompositeMode 
 public int getCompositeMode()
Returns:
the composite mode
o getOffset 
 public double getOffset()
Returns:
the temporal offset of the curve
