  org.datamixer.functions.FunctionStrategy
      org.datamixer.functions.datamixer.ForEachStrategy

public class ForEachStrategy

extends FunctionStrategy

ForEachStrategy takes a nested DatamixerIterator and optionally two attributes: begin and end (integers). If begin and end are given, then ForEachStrategy returns the value returned by iterator.nextValue, for integers starting with begin and ending at end.

If begin and end are not given, then ForEachStrategy returns the value returned by iterator.nextValue, while iterator.hasNext() is true.
