Method Detail

getInputStream

public InputStream getInputStream()
                           throws IOException

Returns an input stream from this MimeBodyPart.

This method applies the appropriate transfer-decoding, based on the Content-Transfer-Encoding attribute of this MimeBodyPart. Thus the returned input stream is a decoded stream of bytes.

This implementation obtains the raw content from the MimeBodyPart using the getContentStream() method and decodes it using the MimeUtility.decode() method.

Specified by:

getInputStream in interface javax.activation.DataSource

Returns:

decoded input stream

Throws:

IOException

getOutputStream

public OutputStream getOutputStream()
                             throws IOException

DataSource method to return an output stream.

This implementation throws the UnknownServiceException.

Specified by:

getOutputStream in interface javax.activation.DataSource

Throws:

IOException

getContentType

public String getContentType()

Returns the content-type of this DataSource.

This implementation just invokes the getContentType method on the MimeBodyPart.

Specified by:

getContentType in interface javax.activation.DataSource

getName

public String getName()

DataSource method to return a name.

This implementation just returns an empty string.

Specified by:

getName in interface javax.activation.DataSource
