MessageHeaders

public MessageHeaders()
               throws MessagingException

Throws:

MessagingException - for failures

public MessageHeaders(InputStream is)
               throws MessagingException

Constructs a MessageHeaders object from the given InputStream.

Parameters:

is - InputStream

Throws:

MessagingException - for failures

Method Details

getSize

public int getSize()

Return the size of this message. Always returns zero.

Specified by:

getSize in interface Part

Overrides:

getSize in class MimeMessage

Returns:

size of content in bytes

getInputStream

public InputStream getInputStream()

Description copied from class: MimeMessage

Return a decoded input stream for this Message's "content".

This implementation obtains the input stream from the DataHandler, that is, it invokes getDataHandler().getInputStream().

Specified by:

getInputStream in interface Part

Overrides:

getInputStream in class MimeMessage

Returns:

an InputStream

See Also:

• MimeMessage.getContentStream()
• DataHandler.getInputStream()

getContentStream

protected InputStream getContentStream()

Description copied from class: MimeMessage

Produce the raw bytes of the content. This method is used during parsing, to create a DataHandler object for the content. Subclasses that can provide a separate input stream for just the message content might want to override this method.

This implementation returns a SharedInputStream, if contentStream is not null. Otherwise, it returns a ByteArrayInputStream constructed out of the content byte array.

Overrides:

getContentStream in class MimeMessage

Returns:

an InputStream containing the raw bytes

See Also:

• MimeMessage.content

setDataHandler

public void setDataHandler(jakarta.activation.DataHandler dh)
                    throws MessagingException

Can't set any content for a MessageHeaders object.

Specified by:

setDataHandler in interface Part

Overrides:

setDataHandler in class MimeMessage

Parameters:

dh - The DataHandler for the content.

Throws:

MessagingException - always
