Constructor Summary

	MimeMultipartEncrypted(javax.activation.DataSource ds) Constructs a MimeMultipartEncrypted object and its bodyparts from the given DataSource.
protected	MimeMultipartEncrypted(java.lang.String contentType) This constructor is used by the createInstance method to create a new instance.

Method Summary

static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted	createInstance(javax.mail.BodyPart bodyPart, de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter) Creates a new instance of this class using bodyPart as the part to be encrypted and encrypter to do the encrypting.
static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted	createInstance(de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter) Creates a new instance of this class using encrypter to do the encrypting.
static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted	createInstance(javax.mail.internet.MimeMultipart multiPart, de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter) Creates a new instance of this class using multiPart as the part to be encrypted and encrypter to do the encrypting.
javax.mail.BodyPart	decrypt(de.buelowssiege.mail.pgp_mime.BodyPartDecrypter decrypter) Decrypts the encrypted bodypart and returns a bodypart containing the decrypted data.
void	setSubType() This method does nothing, as the subtype of this multipart must always be encrypted.
void	writeTo(java.io.OutputStream out) Iterates through all the parts and outputs each mime part separated by a boundary.

Method Detail

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted createInstance(javax.mail.BodyPart bodyPart,
                                                                                  de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter)
                                                                           throws javax.mail.MessagingException

Creates a new instance of this class using bodyPart as the part to be encrypted and encrypter to do the encrypting.

javax.mail.MessagingException

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted createInstance(javax.mail.internet.MimeMultipart multiPart,
                                                                                  de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter)
                                                                           throws javax.mail.MessagingException

Creates a new instance of this class using multiPart as the part to be encrypted and encrypter to do the encrypting.

javax.mail.MessagingException

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartEncrypted createInstance(de.buelowssiege.mail.pgp_mime.BodyPartEncrypter encrypter)
                                                                           throws javax.mail.MessagingException

Creates a new instance of this class using encrypter to do the encrypting. The part to be encrypted must have been set in the encrypter before calling this method.

javax.mail.MessagingException

decrypt

public javax.mail.BodyPart decrypt(de.buelowssiege.mail.pgp_mime.BodyPartDecrypter decrypter)
                            throws javax.mail.MessagingException

Decrypts the encrypted bodypart and returns a bodypart containing the decrypted data.

javax.mail.MessagingException

setSubType

public void setSubType()

This method does nothing, as the subtype of this multipart must always be encrypted.

public void writeTo(java.io.OutputStream out)
             throws javax.mail.MessagingException,
                    java.io.IOException
