FunctionBase Class

Represents a base class for functions.

Namespace: DevExpress.Xpf.Carousel

Assembly: DevExpress.Xpf.Carousel.v18.2.dll

Declaration

C#

public abstract class FunctionBase

VB.NET

Public MustInherit Class FunctionBase

Related API Members

The following members return FunctionBase objects:

• CarouselPanel.OffsetAnimationAddFunction
• CarouselPanel.OffsetDistributionFunction
• Parameter.AnimationAddFunction
• Parameter.AnimationMulFunction
• Parameter.DistributionFunction

Remarks

Each Parameter specifies how a bound property value changes. This is done by combining three functions, as described in Functions and Parameters. These functions are available via Parameter.DistributionFunction, Parameter.AnimationAddFunction and Parameter.AnimationMulFunction properties, which expose FunctionBase descendants.

When declaring a FunctionBase descendant, you need to override its protected GetValueOverride method that simply accepts an argument and returns the function value. This method is called by the public FunctionBase.GetValue method.
