- Method Detail
  - getInputStream
```
public java.io.InputStream getInputStream()
                                   throws java.io.IOException
```
    Returns an input stream from this MimePart.
    This method applies the appropriate transfer-decoding, based on the Content-Transfer-Encoding attribute of this MimePart. Thus the returned input stream is a decoded stream of bytes.
    This implementation obtains the raw content from the Part using the getContentStream() method and decodes it using the MimeUtility.decode() method.
    
    Specified by:
    
    getInputStream in interface DataSource
    
    Returns:
    
    decoded input stream
    
    Throws:
    
    java.io.IOException - for failures creating the InputStream

  - getOutputStream
```
public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException
```
    DataSource method to return an output stream.
    This implementation throws the UnknownServiceException.
    
    Specified by:
    
    getOutputStream in interface DataSource
    
    Returns:
    
    an OutputStream
    
    Throws:
    
    java.io.IOException - for failures creating the OutputStream
  - getContentType
```
public java.lang.String getContentType()
```
    Returns the content-type of this DataSource.
    This implementation just invokes the getContentType method on the MimePart.
    
    Specified by:
    
    getContentType in interface DataSource
    
    Returns:
    
    the MIME Type
  - getName
```
public java.lang.String getName()

    the name of the object.
  - getMessageContext
```
public MessageContext getMessageContext()
```
    Return the MessageContext for the current part.
