Interface Flow

All Superinterfaces:

RuntimeDataMap, java.io.Serializable

public interface Flow
extends RuntimeDataMap, java.io.Serializable

Represents a flow from one action or trigger to another.

A flow may also have a set of signals to raise if it is followed. A signal is a String. The signal will stay raised until a flow is followed that clears the signal. Signals are only visible to the flow chart that raised the signal.
