Package nz.org.riskscape.engine.steps

Class ForeachStep

java.lang.Object

nz.org.riskscape.engine.steps.BaseStep<ForeachStep.Parameters>

nz.org.riskscape.engine.steps.ForeachStep

All Implemented Interfaces:

nz.org.riskscape.engine.Identified, nz.org.riskscape.engine.pipeline.Step

public class ForeachStep
extends BaseStep<ForeachStep.Parameters>

ForeachStep iterates over a static list, executing a child pipeline for each item. The child pipeline automatically has access to: - $item - the current element from the list - $index - the 0-based index of the current iteration

All child pipeline results are combined using UnionStep.
