Constructor Summary

ListFilterCalcStream1(NumberedStream<E> inputStream, Calc1<E,Out> calc1)

Method Summary

Calc1<E,Out>	getCalc1()
java.util.Map.Entry<E,Out>	invoke(E input) Maybe I could make this the predicate method, so if null is returned then don't add anything.
java.util.Map.Entry<E,Out>	invokeIndex(int index) Ignore the index, and iterate over the input stream until a non null value is found.

Constructor Detail

ListFilterCalcStream1

public ListFilterCalcStream1(NumberedStream<E> inputStream,
                             Calc1<E,Out> calc1)

Method Detail

getCalc1

public Calc1<E,Out> getCalc1()

invoke

public java.util.Map.Entry<E,Out> invoke(E input)

Maybe I could make this the predicate method, so if null is returned then don't add anything. Or this could just be the identity.

invokeIndex

public java.util.Map.Entry<E,Out> invokeIndex(int index)

Ignore the index, and iterate over the input stream until a non null value is found.

Overrides:
