- Method Detail
  - async
```
public void async(Runnable runnable)
```
    Executes long operation in dedicated thread. Uses write lock as such operations can't run simultaneously.
    
    Parameters:
    
    runnable - long operation
  - afterAsyncCompletion
```
public <T> T afterAsyncCompletion(IgniteOutClosure<T> closure)
```
    Executes closure that can't run in parallel with long operation that is executed by async(java.lang.Runnable). Uses read lock as such closures can run in parallel with each other.
    
    Type Parameters:
    
    T - return type.
    
    Parameters:
    
    closure - closure.
    
    Returns:
    
    value that is returned by closure.
  - awaitAsyncTaskCompletion
```
public void awaitAsyncTaskCompletion(boolean cancel)
```
    Cancels async tasks.
