Interface Interpolator<P,V>

All Superinterfaces:

javolution.lang.Immutable, java.io.Serializable

All Known Implementing Classes:

Interpolator.Linear

public interface Interpolator<P,V>
extends javolution.lang.Immutable, java.io.Serializable

This interface represents an estimator of the values at a certain point using surrounding points and values. Interpolators are typically used with discrete functions.

As a convenience linear interpolator class for point-values of the same field is provided.

Custom interpolators can be used between Java objects of different kind. For example:[code] // Creates a linear interpolator between the java.util.Date and Measures Interpolator> linear = new Interpolator>() { ... } DiscreteFunction> weight = new DiscreteFunction>(samples, linear, t); [/code]
