  - create
```
<V,C> TaskControl<V> create(Task<V,C> task)
```
    Creates a new TaskControl for a given task. The state is set to Task.State.PENDING and the task is not started. That allows to add listeners for this task execution before starting it.
    Tasks created by this method will fire TaskEvents as appropriate. See TaskListener for details.
    
    Type Parameters:
    
    V -
    
    C -
    
    Parameters:
    
    task -
    
    Returns:
  - getTaskListenerSupport
```
TaskListenerSupport getTaskListenerSupport()
```
    Allows to add listeners.
    
    Returns:
  - getTasks
```
Iterable<TaskControl> getTasks(TaskPredicate predicate)
```
    Returns a collection of all currently created task conforming to the specified predicate. The contract is to have all started and pending tasks available. It's not necessary returning finished tasks.
    
    Parameters:
    
    predicate -
    
    Returns:
  - findTask
```
TaskControl findTask(TaskPredicate predicate)
```
  - getTask
```
TaskControl getTask(String contextId)
```
    Looks up a task by the specified context id.
    
    Parameters:
    
    contextId -
    
    Returns:
  - submit
```
Future<?> submit(Runnable task)
```
    Submits a Runnable object for execution. Contrary to executing Tasks this is more lightweight as it does not fire any events and is not managed by this manager.
    
    Parameters:
    
    task -
    
    Returns:
  - submit
```
<T> Future<T> submit(Callable<T> task)
```
    Submits a Callable object for execution. Contrary to executing Tasks this is more lightweight as it does not fire any events and is not managed by this manager.
    
    Parameters:
    
    task -
    
    Returns:
