Constructor Summary

	MimeMultipartSigned(javax.activation.DataSource ds) Constructs a MimeMultipartSigned object and its bodyparts from the given DataSource.
protected	MimeMultipartSigned(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.MimeMultipartSigned	createInstance(javax.mail.BodyPart bodyPart, de.buelowssiege.mail.pgp_mime.BodyPartSigner signer) Creates a new instance of this class using bodyPart as the part to be signed and signer to do the signing.
static de.buelowssiege.mail.pgp_mime.MimeMultipartSigned	createInstance(de.buelowssiege.mail.pgp_mime.BodyPartSigner signer) Creates a new instance of this class using signer to do the signing.
static de.buelowssiege.mail.pgp_mime.MimeMultipartSigned	createInstance(javax.mail.Multipart multiPart, de.buelowssiege.mail.pgp_mime.BodyPartSigner signer) Creates a new instance of this class using multiPart as the part to be signed and signer to do the signing.
javax.mail.BodyPart	getContentPart() Returns the bodypart which contains the actual content of this signed multipart.
void	setSubType() This method does nothing, as the subtype of this multipart must always be signed.
void	verify(de.buelowssiege.mail.pgp_mime.BodyPartVerifier verifier) Verifies the signature.
void	writeTo(java.io.OutputStream out) Iterates through all the parts and outputs each mime part separated by a boundary.

Constructor Detail

MimeMultipartSigned

public MimeMultipartSigned(javax.activation.DataSource ds)
                    throws javax.mail.MessagingException

Constructs a MimeMultipartSigned object and its bodyparts from the given DataSource.

MimeMultipartSigned

protected MimeMultipartSigned(java.lang.String contentType)
                       throws javax.mail.MessagingException

This constructor is used by the createInstance method to create a new instance.

Method Detail

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartSigned createInstance(javax.mail.BodyPart bodyPart,
                                                                               de.buelowssiege.mail.pgp_mime.BodyPartSigner signer)
                                                                        throws javax.mail.MessagingException

Creates a new instance of this class using bodyPart as the part to be signed and signer to do the signing.

javax.mail.MessagingException

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartSigned createInstance(javax.mail.Multipart multiPart,
                                                                               de.buelowssiege.mail.pgp_mime.BodyPartSigner signer)
                                                                        throws javax.mail.MessagingException

Creates a new instance of this class using multiPart as the part to be signed and signer to do the signing.

javax.mail.MessagingException

createInstance

public static de.buelowssiege.mail.pgp_mime.MimeMultipartSigned createInstance(de.buelowssiege.mail.pgp_mime.BodyPartSigner signer)
                                                                        throws javax.mail.MessagingException

Creates a new instance of this class using signer to do the signing. The part to be signed must have been set in the signer before calling this method.

javax.mail.MessagingException

verify

public void verify(de.buelowssiege.mail.pgp_mime.BodyPartVerifier verifier)
            throws javax.mail.MessagingException

Verifies the signature. An Exception is thrown if the signature is not correct.

javax.mail.MessagingException

getContentPart

public javax.mail.BodyPart getContentPart()
                                   throws javax.mail.MessagingException

Returns the bodypart which contains the actual content of this signed multipart.

javax.mail.MessagingException

setSubType

public void setSubType()

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

writeTo

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

Iterates through all the parts and outputs each mime part separated by a boundary. Before writing to the output stream the updateHeaders method is called.

Overrides:
