org.springframework.scheduling.timer

Class TimerTaskExecutor

java.lang.Object

org.springframework.scheduling.timer.TimerTaskExecutor

All Implemented Interfaces:

java.util.concurrent.Executor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.core.task.AsyncTaskExecutor, org.springframework.core.task.TaskExecutor, SchedulingTaskExecutor

Deprecated.

as of Spring 3.0, in favor of the scheduling.concurrent package which is based on Java 5's java.util.concurrent.ExecutorService

@Deprecated
public class TimerTaskExecutor
extends java.lang.Object
implements SchedulingTaskExecutor, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean

TaskExecutor implementation that uses a single Timer for executing all tasks, effectively resulting in serialized asynchronous execution on a single thread.

Since:

2.0

Constructor Detail

TimerTaskExecutor

public TimerTaskExecutor()

Deprecated.

Create a new TimerTaskExecutor that needs to be further configured and initialized.

See Also:

setTimer(java.util.Timer), afterPropertiesSet()

TimerTaskExecutor

public TimerTaskExecutor(java.util.Timer timer)

Deprecated.

Create a new TimerTaskExecutor for the given Timer.

Parameters:

timer - the Timer to wrap

Method Detail

setTimer

public void setTimer(java.util.Timer timer)

Deprecated.

Set the Timer to use for this TimerTaskExecutor, for example a shared Timer instance defined by a TimerFactoryBean.

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

Parameters:

timer - the Timer to use for this TimerTaskExecutor

See Also:

TimerFactoryBean

setDelay

public void setDelay(long delay)

Deprecated.

Set the delay to use for scheduling tasks passed into the plain 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.

Parameters:

delay - the delay in milliseconds before the task is to be executed

setBeanName

public void setBeanName(java.lang.String beanName)

Deprecated.

Specified by:

setBeanName in interface org.springframework.beans.factory.BeanNameAware

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

createTimer

protected java.util.Timer createTimer()

Deprecated.

Create a new 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.

See Also:

afterPropertiesSet(), Timer.Timer(String, boolean)

getTimer

protected final java.util.Timer getTimer()

Deprecated.

Return the underlying Timer behind this TimerTaskExecutor.

execute

public void execute(java.lang.Runnable task)

Deprecated.

Schedules the given Runnable on this executor's Timer instance, wrapping it in a DelegatingTimerTask.

Specified by:

execute in interface java.util.concurrent.Executor

Specified by:

execute in interface org.springframework.core.task.TaskExecutor

Parameters:

task - the task to be executed

execute

public void execute(java.lang.Runnable task,
           long startTimeout)

Deprecated.

Specified by:

execute in interface org.springframework.core.task.AsyncTaskExecutor

submit

public java.util.concurrent.Future<?> submit(java.lang.Runnable task)

Deprecated.

Specified by:

submit in interface org.springframework.core.task.AsyncTaskExecutor

submit

public <T> java.util.concurrent.Future<T> submit(java.util.concurrent.Callable<T> task)

Deprecated.

Specified by:

submit in interface org.springframework.core.task.AsyncTaskExecutor

prefersShortLivedTasks

public boolean prefersShortLivedTasks()

Deprecated.

This task executor prefers short-lived work units.

Specified by:

prefersShortLivedTasks in interface SchedulingTaskExecutor

Returns:

true if this TaskExecutor prefers short-lived tasks

destroy

public void destroy()

Deprecated.

Cancel the Timer on bean factory shutdown, stopping all scheduled tasks.

Specified by:

destroy in interface org.springframework.beans.factory.DisposableBean

Timer.cancel()
