public BlockedByteArrayOutputStream(BlockedByteArray src,
                                    long pos)
```
    Creates a new stream writing data into the specified blocked byte array.
    
    Parameters:
    
    src - the underlying blocked byte array
    
    pos - the initial position of stream
- Method Detail
  - setPosition
```
void setPosition(long newPos)
```
    Sets the position.
    
    Parameters:
    
    newPos - the new byte position
  - getPosition
```
long getPosition()
```
    Returns the current position.
    
    Returns:
    
    The current byte position.
  - write
```
public void write(int b)
```
    Writes the single byte into the underlying blocked byte array.
    
    Specified by:
    
    write in class java.io.OutputStream
    
    Parameters:
    
    b - the byte to write
  - write
```
public void write(byte[] buf,
                  int offset,
                  int len)
```
    Writes the specified bytes into the underlying blocked byte array.
    
    Overrides:
    
    write in class java.io.OutputStream
    
    Parameters:
    
    buf - source byte array
    
    offset - index of the first byte to write
    
    len - the number of bytes to write
  - close
```
public void close()
```
    Closes the stream.
