Class Mapping<T>

java.lang.Object

com.tagtraum.jipes.AbstractSignalProcessor<T,T>

com.tagtraum.jipes.universal.Mapping<T>

Type Parameters:

T - type to map data from and to

All Implemented Interfaces:

SignalProcessor<T,T>, SignalPullProcessor<T,T>, SignalSource<T>

public class Mapping<T>
extends AbstractSignalProcessor<T,T>

Applies a MapFunction to each provided object of type T (for example to all data of a RealAudioBuffer}). The function could be e.g. a WindowFunction.Hamming window or a Filters.FIRFilter. Due to its universal nature, this is a central SignalProcessor class.
