org.apache.myfaces.trinidad.context.ComponentContextChange
Class that represents a change that is tied to a component in the component tree. This class is used by {@link ComponentContextManager} to be able to suspend and resumethe context of a component during an invoke on component or visit tree call.
Note that implementing classes are encouraged to override the to string function to describe the change. This enhances the ability to debug should the stack ever become out of sync.
