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 javax.activation.DataSource

Returns:

decoded input stream

Throws:

java.io.IOException
