Class AperiodicEventHandler

java.lang.Object

javax.safetycritical.ManagedEventHandler

javax.safetycritical.AperiodicEventHandler

All Implemented Interfaces:

ManagedSchedulable

@SCJAllowed(value=LEVEL_1)
public abstract class AperiodicEventHandler
extends ManagedEventHandler

This class permits the explicit release of application code. Concrete subclasses must implement the handleAsyncEvent method and may override the default cleanUp method.
Note that the values in parameters passed to the constructors are those that will be used by the infrastructure. Changing these values after construction will have no impact on the created event handler.
