Examples of TaskExecutor

cl.niclabs.skandium.system.TaskExecutor
This class is an extension of {@link ThreadPoolExecutor}, but with custom @{link #beforeExecute} and #{link #afterExecute} methods to manipulate taske execution. @author mleyton
it.geosolutions.geobatch.task.TaskExecutor
it.sauronsoftware.cron4j.TaskExecutor

Represents a task executor, which is something similar to threads.

Each time a task is launched, a new executor is spawned, executing and watching the task

Alive task executors can be retrieved with the {@link Scheduler#getExecutingTasks()} method, and they expose method tocontrol the ongoing execution.

org.apache.examples.panorama.startup.impl.TaskExecutor
A service that executes a series of {@link org.apache.examples.panorama.startup.impl.Task}s. Tasks have an ordering based on pre- and post-requisites. @author Howard Lewis Ship
org.apache.helix.messaging.handling.TaskExecutor
org.apache.qpid.server.configuration.updater.TaskExecutor
org.jamesii.gui.application.task.TaskExecutor
Class that can execute {@link ITask}s using a thread pool while respecting blocking requirement of given tasks. This executor is thread safe.
Because of using a thread pool and the ability to block The user must take care of the following requirements:
- tasks should not synchronize between each other due to the risk of dead locks
- blocking tasks should only be used if they are really needed because they are blocking subsequent tasks from executing

org.springframework.core.task.TaskExecutor
Simple task executor interface that abstracts the execution of a {@link Runnable}.
Implementations can use all sorts of different execution strategies, such as: synchronous, asynchronous, using a thread pool, and more.
Equivalent to JDK 1.5's {@link java.util.concurrent.Executor}interface; extending it now in Spring 3.0, so that clients may declare a dependency on an Executor and receive any TaskExecutor implementation. This interface remains separate from the standard Executor interface mainly for backwards compatibility with JDK 1.4 in Spring 2.x. @author Juergen Hoeller @since 2.0 @see java.util.concurrent.Executor
