public class MimeMessage

extends Message

implements MimePart

This class represents a MIME style email message. It implements the Message abstract class and the MimePart interface.

Clients wanting to create new MIME style messages will instantiate an empty MimeMessage object and then fill it with appropriate attributes and content.

Service providers that implement MIME compliant backend stores may want to subclass MimeMessage and override certain methods to provide specific implementations. The simplest case is probably a provider that generates a MIME style input stream and leaves the parsing of the stream to this class.

MimeMessage uses the InternetHeaders class to parse and store the toplevel RFC 822 headers of a message.

A note on RFC 822 and MIME headers

RFC 822 header fields must contain only US-ASCII characters. MIME allows non ASCII characters to be present in certain portions of certain headers, by encoding those characters. RFC 2047 specifies the rules for doing this. The MimeUtility class provided in this package can be used to to achieve this. Callers of the setHeader, addHeader, and addHeaderLine methods are responsible for enforcing the MIME requirements for the specified headers. In addition, these header fields must be folded(wrapped) before being sent if they exceed the line length limitation for the transport(1000 bytes for SMTP). Received headers may have been folded. The application is responsible for folding and unfolding headers as appropriate.

content

protected byte[] content

Byte array that holds the bytes of this Message's content.

contentStream

protected InputStream contentStream

If the data for this message was supplied by an InputStream that implements the SharedInputStream interface, contentStream is another such stream representing the content of this message. In this case, content will be null.

dh

protected DataHandler dh

The DataHandler object representing this Message's content.

flags

protected Flags flags

The Flags for this message.

headers

protected InternetHeaders headers

The InternetHeaders object that stores the header of this message.

modified

protected boolean modified

A flag indicating whether the message has been modified. If the message has not been modified, any data in the content array is assumed to be valid and is used directly in the writeTo method. This flag is set to true when an empty message is created or when the saveChanges method is called.

saved

protected boolean saved

Does the saveChanges method need to be called on this message? This flag is set to false by the public constructor and set to true by the saveChanges method. The writeTo method checks this flag and calls the saveChanges method as necessary. This avoids the common mistake of forgetting to call the saveChanges method on a newly constructed message.

This implementation just returns a ByteArrayInputStream constructed out of the content byte array.
See Also:
MimeBodyPart.getContentStream()

getContentType

public String getContentType()
            throws MessagingException

Returns the value of the RFC 822 "Content-Type" header field. This represents the content-type of the content of this message. This value must not be null. If this field is unavailable, "text/plain" should be returned.

isSet in interface Message
Parameters:
flag - - the flag
Returns:
value of the specified flag for this message

parse

protected void parse(InputStream is)
            throws MessagingException

Parse the InputStream setting the headers and content fields appropriately. Also resets the modified flag.
This method is intended for use by subclasses that need to control when the InputStream is parsed.
Parameters:
is - The message input stream

removeHeader

public void removeHeader(String name)
            throws MessagingException

Remove all headers with this name.
Specified by:
removeHeader in interface Part
Parameters:
name - header name

reply

public Message reply(boolean replyToAll)
            throws MessagingException

Get a new Message suitable for a reply to this message. The new Message will have its attributes and headers set up appropriately. Note that this new message object will be empty, i.e., it will not have a "content". These will have to be suitably filled in by the client.
If replyToAll is set, the new Message will be addressed to all recipients of this message. Otherwise, the reply will be addressed to only the sender of this message(using the value of the getReplyTo method).
The "Subject" field is filled in with the original subject prefixed with "Re:"(unless it already starts with "Re:"). The "In-Reply-To" header is set in the new message if this message has a "Message-Id" header. The ANSWERED flag is set in this message.
Overrides:
reply in interface Message
Parameters:
replyToAll - reply should be sent to all recipients of this message
Returns:
the reply Message

saveChanges

public void saveChanges()
            throws MessagingException

Updates the appropriate header fields of this message to be consistent with the message's contents. If this message is contained in a Folder, any changes made to this message are committed to the containing folder.
If any part of a message's headers or contents are changed, saveChanges must be called to ensure that those changes are permanent. Otherwise, any such modifications may or may not be saved, depending on the folder implementation.
Messages obtained from folders opened READ_ONLY should not be modified and saveChanges should not be called on such messages.
This method sets the modified flag to true, the save flag to true, and then calls the updateHeaders method.
Overrides:
saveChanges in interface Message

public void setContent(Object o,
                       String type)
            throws MessagingException

A convenience method for setting this Message'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. i.e., 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.

Note that there may be a performance penalty if text is large, since this method may have to scan all the characters to determine what charset to use.
If the charset is already known, use the setText method that takes the charset parameter.
Specified by:
setText in interface MimePart
setText in interface Part
See Also:
MimeBodyPart.setText

setText

public void setText(String text,
                    String charset)

updateHeaders

protected void updateHeaders()
            throws MessagingException

Called by the saveChanges method to actually update the MIME headers. The implementation here sets the Content-Transfer-Encoding header (if needed and not already set), the Mime-Version header and the Message-ID header. Also, if the content of this message is a MimeMultipart, its updateHeaders method is called.
See Also:
MimeBodyPart.updateHeaders()

writeTo

public void writeTo(OutputStream os)
            throws IOException,
                   MessagingException

Output the message as an RFC 822 format stream.
Note that, depending on how the message was constructed, it may use a variety of line termination conventions. Generally the output should be sent through an appropriate FilterOutputStream that converts the line terminators to the desired form, either CRLF for MIME compatibility and for use in Internet protocols, or the local platform's line terminator for storage in a local text file.
This implementation calls the writeTo(OutputStream, String[]) method with a null ignore list.
Specified by:
writeTo in interface Part

writeTo

public void writeTo(OutputStream os,
                    String[] ignoreList)
            throws IOException,
                   MessagingException

Output the message as an RFC 822 format stream, without specified headers. If the saved flag is not set, the saveChanges method is called. If the modified flag is not set and the content array is not null, the content array is written directly, after writing the appropriate message headers.
