```
    This method handle the processing of all Selector's interest op (OP_ACCEPT,OP_READ,OP_WRITE,OP_CONNECT) by delegating to its Handler. By default, all java.nio.channels.Selector operations are implemented using SelectorHandler. All SelectionKey operations are implemented by SelectionKeyHandler. Finally, ProtocolChain creation/re-use are implemented by InstanceHandler.
  - getPendingTasks
```
public Queue<SelectorHandlerTask> getPendingTasks()
```
  - getPostponedTasks
```
public Queue<SelectorHandlerTask> getPostponedTasks()
```
  - obtainPostponedTasks
```
public Queue<SelectorHandlerTask> obtainPostponedTasks()
```
  - getLastSelectedKeysCount
```
public int getLastSelectedKeysCount()
```
    Number of SelectionKeys, which were selected last time. Operation is not thread-safe.
    
    Returns:
    number of SelectionKeys, which were selected last time.
  - switchToNewSelector
```
protected final void switchToNewSelector()
                                  throws IOException
```
    Throws:
    
    IOException
