    numBytes - The number of bytes to skip.
    
    Throws:
    
    IOException - Thrown, if any I/O related problem occurred such that the view could not be advanced to the desired position.
  - write
```
void write(DataInputView source,
           int numBytes)
    throws IOException
```
    Copies numBytes bytes from the source to this view.
    
    Parameters:
    
    source - The source to copy the bytes from.
    
    numBytes - The number of bytes to copy.
    
    Throws:
    
    IOException - Thrown, if any I/O related problem occurred, such that either the input view could not be read, or the output could not be written.
