```
- Method Detail
  - initialize
```
public void initialize()
```
    Description copied from interface: Operation
    
    Initialize this operation. This is used to prepare output byte buffers and stuff.
    
    Specified by:
    
    initialize in interface Operation
    
    Specified by:
    
    initialize in class TapOperationImpl
  - readFromBuffer
```
public void readFromBuffer(java.nio.ByteBuffer data)
```
    Description copied from class: OperationImpl
    
    Read from the incoming ByteBuffer. Reading from the buffer is done in stages, depending on how much data can be read at once. First, the header is read and then parsed (24 bytes, indicated by OperationImpl.MIN_RECV_PACKET). Then, the payload is read (if one is available for this operation and can be loaded fully).
    
    Specified by:
    
    readFromBuffer in interface Operation
    
    Overrides:
    
    readFromBuffer in class TapOperationImpl
    
    Parameters:
    
    data - the buffer to read from.
  - streamClosed
```
public void streamClosed(OperationState state)
```
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class OperationImpl
