scheduling.concurrent
package which is based on Java 5's java.util.concurrent.ExecutorService
@Deprecated public class TimerTaskExecutor
TaskExecutor implementation that uses a
single Timer for executing all tasks, effectively resulting in
serialized asynchronous execution on a single thread.

If not specified, a default internal Timer instance will be used.

execute(Runnable) method. Default is 0.
Note that calls to execute(Runnable, long) will use the
given timeout as delay if it is lower than the general delay.
delay - the delay in milliseconds before the task is to be executedpublic void setBeanName(String beanName)
BeanNameAwareInvoked after population of normal bean properties but before an
init callback such as InitializingBean.afterPropertiesSet()
or a custom init-method.
setBeanName in interface BeanNameAwarebeanName - the name of the bean in the factory.
Note that this name is the actual bean name used in the factory, which may
differ from the originally specified name: in particular for inner bean
names, the actual bean name might have been made unique through appending
"#..." suffixes. Use the BeanFactoryUtils.originalBeanName(String)
method to extract the original bean name (without suffix), if desired.public void afterPropertiesSet()
InitializingBeanThis 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.
afterPropertiesSet in interface InitializingBeanprotected Timer createTimer()
Timer instance. Called by afterPropertiesSet
if no Timer has been specified explicitly.
The default implementation creates a plain non-daemon Timer.
If overridden, subclasses must take care to ensure that a non-null
Timer is returned from the execution of this method.

supposed to start. This is intended as a hint to the executor, allowing for
