Interface for user-written actions. An Action object that instantiates a user-written action class is used as an argument to the EventRegistration constructor. The user-written class, which is in the CLASSPATH of the T3Server, is dynamically loaded into the T3Server the first time any registration specifies it.
Because the Java class loader does not permit the passing of arguments to the constructors of dynamically loaded classes, the constructor for any user-written class that implements this interface must be a default constructor, that is, one that takes no arguments. The user-written registerInit() method takes the registration parameters as an input argument and allows the newly-constructed action object to inspect and act upon the registration parameters at the time of registration.
Note: The isLongRunning() method is deprecated in release 2.5. Users no longer need to implement this method in classes that implement this interface.
