- Method Detail
  - execute
```
Future execute(TLspTaskExecutorRunnable aTaskExecutorRunnable)
```
    Schedules the supplied Runnable for execution. The actual execution may take place at some unspecified point in the future. This method therefore returns a Future which can be used to query the progress of the task. A return value of null indicates that the task was already executed when this method returned.
    
    Parameters:
    
    aTaskExecutorRunnable - the task to be executed
    
    Returns:
    
    a Future for following up on the task
  - flush
```
void flush()
```
    Blocks until all currently pending tasks have finished.
  - abort
```
void abort()
```
    Attempts to cancel all currently pending tasks and blocks until the task queue is empty.
  - destroy
```
void destroy()
```
    Calls abort() and renders the task executor invalid to use.
  - addTaskListener
```
void addTaskListener(ILspTaskExecutorListener aTaskExecutorListener)
```
    Adds a task listener to this task executor. The task listener will be notified of any changes in tasks.
    
    Parameters:
    
    aTaskExecutorListener - a task executor listener that will be notified of task updates
  - removeTaskListener
```
void removeTaskListener(ILspTaskExecutorListener aTaskExecutorListener)
```
    Removes a task listener from this task executor. The task listener will no longer be notified of any changes in tasks.
    
    Parameters:
    
    aTaskExecutorListener - a task executor listener that will no longer be notified of task updates
