MimePartDataSource

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

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

MimeMessage.getContentStream(), MimeBodyPart.getContentStream(), MimeUtility.decode(java.io.InputStream, java.lang.String)

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 javax.activation.DataSource
Throws:
java.io.IOException

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 javax.activation.DataSource

getName

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

This implementation just returns an empty string.

Specified by:
