Class ComponentPropertiesHelper

java.lang.Object

org.chenile.stm.impl.ComponentPropertiesHelper

public final class ComponentPropertiesHelper
extends Object

A helper class to obtain the properties for the current action (as passed in the flow context). This class is aware of the current scripting strategy and uses it to transform the incoming property.

This is useful to support component properties whose values are based on the flow context passed to the STM.
