Class CombinedStreamFunction<AIN,AOUT,BIN,BOUT>

java.lang.Object

org.openimaj.util.stream.combine.CombinedStreamFunction<AIN,AOUT,BIN,BOUT>

Type Parameters:

AIN - The first part of the input pair

BIN - The second part of the input pair

AOUT - The first part of the output pair

BOUT - The second part of the output pair

All Implemented Interfaces:

Function<IndependentPair<AIN,BIN>,IndependentPair<AOUT,BOUT>>

public class CombinedStreamFunction<AIN,AOUT,BIN,BOUT>
extends Object
implements Function<IndependentPair<AIN,BIN>,IndependentPair<AOUT,BOUT>>

Given a combined stream (i.e. a stream of IndependentPair instances) apply two functions (one to each component of the pair) to produce a stream of output pairs.
