All Implemented Interfaces:

java.lang.Runnable
```
public class BioReplicationTask
extends AbstractRxTask
```
A worker thread class which can drain channels and echo-back the input. Each instance is constructed with a reference to the owning thread pool object. When started, the thread loops forever waiting to be awakened to service the channel associated with a SelectionKey object. The worker is tasked by calling its serviceChannel() method with a SelectionKey object. The serviceChannel() method stores the key reference in the thread object then calls notify() to wake it up. When the channel has been drained, the worker thread returns itself to its parent pool.

    The actual code which drains the channel associated with the given key. This method assumes the key has been modified prior to invocation to turn off selection interest in OP_READ. When this method completes it re-enables OP_READ and calls wakeup() on the selector so the selector will resume watching this channel.
    
    Throws:
    
    java.lang.Exception
  - sendAck
```
protected void sendAck(byte[] command)
```
    send a reply-acknowledgment (6,2,3)
    
    Parameters:
    command -
  - close
```
public void close()

    Overrides:
