Class StepMatrix

java.lang.Object
  org.norther.tammi.spray.template.flow.StepMatrix

All Implemented Interfaces:

Serializable, Cloneable

public class StepMatrix
extends Object
implements Cloneable, Serializable

Allowed routes between template flows and their steps are defined by BitSet matrix of size (n+1)*(n+1), where n is the number of steps in a flow. Index 0 is reserved to define access to step into and out from the flow.
