Interface Interpolator<P,V>

All Superinterfaces:

Immutable, java.io.Serializable

All Known Implementing Classes:

Interpolator.Linear

public interface Interpolator<P,V>
extends 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:

     // Creates a linear interpolator between the java.util.Date and Measures<Mass>
     Interpolator<Date, Measure<Mass>> linear 
          = new Interpolator<Date, Measure<Mass>>() { ... }
     DiscreteFunction<Date, Measure<Mass>> weight 
         = new DiscreteFunction<Date, Measure<Mass>>(samples, linear, t);

Nested Class Summary

static class

Interpolator.Linear<F extends Field<F>> This class represents a linear interpolator for field instances (point and values from the same field).

Method Summary

V	interpolate(P point, java.util.SortedMap<P,V> pointValues) Estimates the value at the specified point.

Method Detail

interpolate

V interpolate(P point,
              java.util.SortedMap<P,V> pointValues)

Estimates the value at the specified point.

Parameters:

point - the point for which the value is estimated.

pointValues - the point-value entries.

Returns:

the estimated value at the specified point.
