      • getDescription

        public java.lang.String getDescription()
                                throws MessagingException
        Description copied from class: MimeBodyPart
        Returns the "Content-Description" header field of this body part. This typically associates some descriptive information with this part. Returns null if this field is unavailable or its value is absent.

        If the Content-Description field is encoded as per RFC 2047, it is decoded and converted into Unicode. If the decoding or conversion fails, the raw data is returned as is.

        This implementation uses getHeader(name) to obtain the requisite header field.

        Specified by:
        getDescription in interface Part
        Overrides:
        getDescription in class MimeBodyPart
        Returns:

      • setDescription

        public void setDescription​(java.lang.String description,
                           java.lang.String charset)
                    throws MessagingException
        Description copied from class: MimeBodyPart
        Set the "Content-Description" header field for this body part. If the description parameter is null, then any existing "Content-Description" fields are removed.

        If the description contains non US-ASCII characters, it will be encoded using the specified charset. If the description contains only US-ASCII characters, no encoding is done and it is used as is.

        Note that if the charset encoding process fails, a MessagingException is thrown, and an UnsupportedEncodingException is included in the chain of nested exceptions within the MessagingException.

        Overrides:
        setDescription in class MimeBodyPart
        Parameters:
        description - Description
        charset - Charset for encoding
        Throws:
        IllegalWriteException - if the underlying implementation does not support modification
        MessagingException - otherwise; an UnsupportedEncodingException may be included in the exception chain if the charset conversion fails.

      • getFileName

        public java.lang.String getFileName()
                             throws MessagingException
        Description copied from class: MimeBodyPart
        Get the filename associated with this body part.

        Returns the value of the "filename" parameter from the "Content-Disposition" header field of this body part. If its not available, returns the value of the "name" parameter from the "Content-Type" header field of this body part. Returns null if both are absent.

        If the mail.mime.decodefilename System property is set to true, the MimeUtility.decodeText method will be used to decode the filename. While such encoding is not supported by the MIME spec, many mailers use this technique to support non-ASCII characters in filenames. The default value of this property is false.

        Specified by:
        getFileName in interface Part
        Overrides:
        getFileName in class MimeBodyPart
        Returns:
        filename
        Throws:
        MessagingException - for failures

      • setFileName

        public void setFileName​(java.lang.String filename)
                 throws MessagingException
        Description copied from class: MimeBodyPart
        Set the filename associated with this body part, if possible.

        Sets the "filename" parameter of the "Content-Disposition" header field of this body part. For compatibility with older mailers, the "name" parameter of the "Content-Type" header is also set.

        If the mail.mime.encodefilename System property is set to true, the MimeUtility.encodeText method will be used to encode the filename. While such encoding is not supported by the MIME spec, many mailers use this technique to support non-ASCII characters in filenames. The default value of this property is false.

        Specified by:
        setFileName in interface Part
        Overrides:
        setFileName in class MimeBodyPart
        Parameters:
        filename - the file name
        Throws:
        IllegalWriteException - if the underlying implementation does not support modification
        MessagingException - for other failures

        public void setContent​(java.lang.Object o,
                       java.lang.String type)
                throws MessagingException
        Description copied from class: MimeBodyPart
        A convenience method for setting this body part's content.

        The content is wrapped in a DataHandler object. Note that a DataContentHandler class for the specified type should be available to the JavaMail implementation for this to work right. That is, to do setContent(foobar, "application/x-foobar"), a DataContentHandler for "application/x-foobar" should be installed. Refer to the Java Activation Framework for more information.

        Specified by:
        setContent in interface Part
        Overrides:
        setContent in class MimeBodyPart
