Class NamedListCalcStream1<In,E>

  org.shapelogic.streams.BaseCommonStream<E>
      org.shapelogic.streams.BaseListCommonStream<E>

              org.shapelogic.streams.NamedListCalcStream1<In,E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Iterator<E>, Calc1<In,E>, CalcValue<E>, ContextGettable, LazyCalc<E>, RecursiveContext, InputStream1<In,E>, ListStream<E>, NumberedStream<E>, Stream<E>, StreamProperties

public class NamedListCalcStream1<In,E>
extends BaseListStream1<In,E>

Make a stream that is using a Calc1 class to do a calculation, based on a named input stream stored in a context.
Uses lazy setup so input stream does not have to exist when stream is created.
There should be a way to say whether you have to calculate all the values sequentially to use this.

Method Detail

setup

public void setup()

Description copied from interface: LazyCalc

Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.

Specified by:

setup in interface LazyCalc<E>

Overrides:

setup in class BaseCommonStream<E>

invoke

public E invoke(In input)

getInputStream

public NumberedStream<In> getInputStream()

Description copied from interface: InputStream1

Stream that this stream is connected to. What if the Range is of different type? I think that maybe I can relax this later.

Specified by:

getInputStream in interface InputStream1<In,E>

Overrides:

getInputStream in class BaseListStream1<In,E>

setCalc

public void setCalc(Calc1<In,E> calc)
