Constructor Details

MimePartDataSource

public MimePartDataSource(MimePart part)
Constructor, that constructs a DataSource from a MimePart.

Method Details

getContentType

public String getContentType()
Returns the content-type of this DataSource.

This implementation just invokes the getContentType method on the MimePart.


getInputStream

public InputStream getInputStream()
            throws 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.

Returns:
decoded input stream

getMessageContext

public MessageContext getMessageContext()
Return the MessageContext for the current part.
Specified by:
getMessageContext in interface MessageAware

getName

public String getName()
DataSource method to return a name.

This implementation just returns an empty string.

            throws IOException
DataSource method to return an output stream.
