Examples of org.apache.commons.scxml2.env.SimpleScheduler

org.apache.commons.scxml2.TriggerEvent

EventDispatcher implementation that can schedule delayed <send> events for the "scxml" type attribute value (which is also the default). This implementation uses J2SE Timers.

No other types are processed. Subclasses may support additional types by overriding the send(...) and cancel(...) methods and delegating to their super counterparts for the "scxml" type.
