    Returns:
    
    The encoded buffer.

    Encode this Data for the default wire format WireFormat.getDefaultWireFormat(). Also set the defaultWireEncoding field to the encoded result.
    
    Returns:
    
    The encoded buffer.
  - wireDecode

    Parameters:
    
    input - The input Blob to decode. This reads from buf().position() to buf().limit(), but does not change the position.
    
    wireFormat - A WireFormat object used to decode the input.

    Parameters:
    
    input - The input Blob to decode. This reads from buf().position() to buf().limit(), but does not change the position.
    
    Throws:

```
    Decode the input using a particular wire format and update this Data. If wireFormat is the default wire format, also set the defaultWireEncoding field to a copy of the input. (To not copy the input, see wireDecode(Blob).)
    
    Parameters:
    
    input - The input buffer to decode. This reads from position() to limit(), but does not change the position.
    
    wireFormat - A WireFormat object used to decode the input.
    
    Throws:
    
    EncodingException - For invalid encoding.
  - wireDecode

                      throws EncodingException
```
    Decode the input using the default wire format WireFormat.getDefaultWireFormat() and update this Data. Also set the defaultWireEncoding field to the input.
    
    Parameters:
    
    input - The input buffer to decode. This reads from position() to limit(), but does not change the position.
