java.lang.Objectorg.springframework.scheduling.timer.TimerFactoryBean
FactoryBean that sets up a J2SE Timer and exposes it for bean references.
Allows registration of ScheduledTimerTasks, automatically starting the timer on initialization and cancelling it on destruction. In typical scenarios, there is no need to access the Timer instance itself in application code.
Note that Timer uses a TimerTask instance that is shared between repeated executions, in contrast to Quartz which instantiates a new Job for each execution.

Method Summary | |
void |
afterPropertiesSet()
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware). |
protected java.util.Timer |
createTimer(boolean daemon)
Create a new Timer instance. |
void |
destroy()
This implementation cancels the Timer, stopping all scheduled tasks. |
java.lang.Object |
getObject()
Return an instance (possibly shared or independent) of the object managed by this factory. |
java.lang.Class |
getObjectType()
Return the type of object that this FactoryBean creates, or null if not known in advance. |
boolean |
isSingleton()
Is the bean managed by this factory a singleton or a prototype? |
void |
setDaemon(boolean daemon)
Set whether the timer should use a daemon thread, just executing as long as the application itself is running. |
void |
setScheduledTimerTasks(ScheduledTimerTask[] scheduledTimerTasks)
Register a list of ScheduledTimerTask objects with the Timer that this FactoryBean creates. |

InitializingBean
This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

public java.lang.Class getObjectType()
FactoryBean
For a singleton, this can simply return getObject().getClass(), or even null, as autowiring will always check the actual objects for singletons. For prototypes, returning a meaningful type here is highly advisable, as autowiring will simply ignore them else.

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory.
