Class TaskManager<C extends ApplicationContext>

java.lang.Object

de.esprit.common.util.DumpableObject

de.esprit.appsuite.launch.AbstractApplicationObject<C>

de.esprit.appsuite.task.taskmgr.TaskManager<C>

All Implemented Interfaces:

ApplicationObject<C>, CloseableComponent, SimpleLogSupport, Dumpable, java.lang.AutoCloseable

Direct Known Subclasses:

ClientTaskManager, ServerTaskManager

public class TaskManager<C extends ApplicationContext>
extends AbstractApplicationObject<C>
implements CloseableComponent

This class maintains a Map with references to all running cancellable AsyncTasks in order to be able to access them by TaskId and cancel them at any time. It also maintains a ActiveTasksListModel which keeps references to the RunStateFlag of the currently running tasks. This ListModel is linked to the taskMap for canceling tasks.

Method Detail

getAsyncExecutor

public java.util.concurrent.ThreadPoolExecutor getAsyncExecutor()

getActiveTasksListModel

public ActiveTasksListModel getActiveTasksListModel()

getActiveWorkflowsListModel

public ActiveWorkflowsListModel getActiveWorkflowsListModel()

getActiveOsProcessesListModel

public ActiveOsProcessesListModel getActiveOsProcessesListModel()

cancelAll

public int cancelAll()

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

cancelTask

public boolean cancelTask(TaskId taskId)

Cancels the running task by TaskId.

Returns:

true if the task was found and cancelled, false if the task was not found

findTask

public final AsyncTask findTask(TaskId taskId)

findTaskByName

public AsyncTask findTaskByName(java.lang.String taskName)

registerTask

public void registerTask(AsyncTask task)

deregisterTask

public void deregisterTask(AsyncTask task)

getTaskCount

public int getTaskCount()

findAllCancellableTaskIds

public final java.util.List<TaskId> findAllCancellableTaskIds()

Returns a List of all TaskIds that are registered for cancellation.

findAllNonCancellableTaskIds

public java.util.List<TaskId> findAllNonCancellableTaskIds()

Returns a List of all TaskIds that are registered but uncancellable.

fillCurrentActivity

public void fillCurrentActivity(java.util.Map<java.lang.String,java.lang.Integer> activityMap)

Stores the current item-count in the given activityMap. This is just a snapshot - you should not rely on the counts to be valid over time.

checkForActivity

protected final void checkForActivity(java.util.Map<java.lang.String,java.lang.Integer> activityMap,
                    ActivityListModel listModel)

Adds the count of active async components to the activityMap

registerTaskStateChange

public void registerTaskStateChange(RunStateFlag stateFlag)
