Class NNTPMessage

public Enumeration getAllHeaderLines()
            throws MessagingException

Get all header lines as an Enumeration of Strings. A Header line is a raw RFC 822 header-line, containing both the "name" and "value" field.

Specified by:

getAllHeaderLines in interface MimePart

Overrides:

getAllHeaderLines in interface MimeMessage

public Enumeration getAllHeaders()
            throws MessagingException

Return all the headers from this Message as an enumeration of Header objects.

Note that certain headers may be encoded as per RFC 2047 if they contain non US-ASCII characters and these should be decoded.

This implementation obtains the headers from the headers InternetHeaders object.

Specified by:

getAllHeaders in interface Part

Overrides:

getAllHeaders in interface MimeMessage

Returns:

array of header objects

public InputStream getContentStream()
            throws MessagingException

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 just returns a ByteArrayInputStream constructed out of the content byte array.

Overrides:

getContentStream in interface MimeMessage

MimeBodyPart.getContentStream()

public String[] getHeader(String name)
            throws MessagingException

Get all the headers for this header_name. Note that certain headers may be encoded as per RFC 2047 if they contain non US-ASCII characters and these should be decoded.

This implementation obtains the headers from the headers InternetHeaders object.

Specified by:

getHeader in interface Part

Overrides:

getHeader in interface MimeMessage

Parameters:

name - name of header

Returns:

array of headers

public String getHeader(String name,
                        String delimiter)
            throws MessagingException

Get all the headers for this header name, returned as a single String, with headers separated by the delimiter. If the delimiter is null, only the first header is returned.

Specified by:

getHeader in interface MimePart

Overrides:

getHeader in interface MimeMessage

Parameters:

name - the name of the header

delimiter - the delimiter

Returns:

the value fields for all headers with this name

public int getLineCount()
            throws MessagingException

Return the number of lines for the content of this message. Return -1 if this number cannot be determined.

Note that this number may not be an exact measure of the content length and may or may not account for any transfer encoding of the content.

This implementation returns -1.

Specified by:

getLineCount in interface Part

Overrides:

getLineCount in interface MimeMessage

public Enumeration getMatchingHeaderLines(String[] names)
            throws MessagingException

Get matching header lines as an Enumeration of Strings. A Header line is a raw RFC 822 header-line, containing both the "name" and "value" field.

Specified by:

getMatchingHeaderLines in interface MimePart

Overrides:

getMatchingHeaderLines in interface MimeMessage

public Enumeration getMatchingHeaders(String[] names)
            throws MessagingException

Return matching headers from this Message as an Enumeration of Header objects.

This implementation obtains the headers from the headers InternetHeaders object.

Specified by:

getMatchingHeaders in interface Part

Overrides:

getMatchingHeaders in interface MimeMessage

public Enumeration getNonMatchingHeaderLines(String[] names)
            throws MessagingException

Get non-matching header lines as an Enumeration of Strings. A Header line is a raw RFC 822 header-line, containing both the "name" and "value" field.

Specified by:

getNonMatchingHeaderLines in interface MimePart

Overrides:

getNonMatchingHeaderLines in interface MimeMessage

public Enumeration getNonMatchingHeaders(String[] names)
            throws MessagingException

Return non-matching headers from this Message as an Enumeration of Header objects.

This implementation obtains the headers from the headers InternetHeaders object.

Specified by:

getNonMatchingHeaders in interface Part

Overrides:

getNonMatchingHeaders in interface MimeMessage

public int getSize()
            throws MessagingException

Return the size of the content of this message in bytes. Return -1 if the size cannot be determined.

Note that this number may not be an exact measure of the content size and may or may not account for any transfer encoding of the content.

This implementation returns the size of the content array (if not null), or, if contentStream is not null, and the available method returns a positive number, it returns that number as the size. Otherwise, it returns -1.

Specified by:

getSize in interface Part

Overrides:

getSize in interface MimeMessage

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 MimeMessage

public void setFlags(Flags flag,
                     boolean set)
            throws MessagingException

Set the flags for this message.

This implementation modifies the flags field.

Overrides:

setFlags in interface MimeMessage
