- org.simpleframework.common.thread.ConcurrentExecutor
-
- All Implemented Interfaces:
java.util.concurrent.Executor
public class ConcurrentExecutor extends java.lang.Object implements java.util.concurrent.Executor
TheConcurrentExecutor
object is used to execute tasks in a thread pool. This creates a thread pool with an unbounded list of outstanding tasks, which ensures that any system requesting a task to be executed will not block when handing it over.

ConcurrentExecutor
public ConcurrentExecutor(java.lang.Class type)
Constructor for theConcurrentExecutor
object. This is used to create a pool of threads that can be used to execute arbitraryRunnable
tasks. If the threads are busy this will simply enqueue the tasks and return.- Parameters:
type
- this is the type of runnable that this accepts

tasks. If the threads are busy this will simply enqueue the tasks and return.- Parameters:
type
- this is the type of runnable that this acceptssize

execute
public void execute(java.lang.Runnable task)
Theexecute
method is used to queue the task for execution. If all threads are busy the provided task is queued and waits until all current and outstanding tasks are finished.- Specified by:
execute
in interfacejava.util.concurrent.Executor
- Parameters:
task
- this is the task to be queued for execution
-
stop
public void stop()
This is used to stop the executor by interrupting all running tasks and shutting down the threads within the pool. This will return once it has been stopped, and no further tasks will be accepted by this pool for execution.
-
stop
public void stop(long wait)
This is used to stop the executor by interrupting all running tasks and shutting down the threads within the pool. This will return once it has been stopped, and no further tasks will be accepted by this pool for execution.- Parameters:
wait
- the number of milliseconds to wait for it to stop
