Examples of org.springframework.webflow.execution.Event

org.springframework.webflow.execution.Event
Signals the occurrence of something an active flow execution should respond to. Each event has a string id that provides a key for identifying what happened: e.g "coinInserted", or "pinDropped". Events may have attributes that provide arbitrary payload data, e.g. "coin.amount=25", or "pinDropSpeed=25ms".
As an example, a "submit" event might signal that a Submit button was pressed in a web browser. A "success" event might signal an action executed successfully. A "finish" event might signal a subflow ended normally.
Why is this not an interface? A specific design choice. An event is not a strategy that defines a generic type or role--it is essentially an immutable value object. It is expected that specializations of this base class be "Events" and not part of some other inheritance hierarchy. @author Keith Donald @author Erwin Vervaet @author Colin Sampaleanu
