Interface MimePart

All Superinterfaces:
Part
All Known Implementing Classes:
MimeBodyPart, MimeMessage, PreencodedMimeBodyPart

public interface MimePart
extends Part

The MimePart interface models an Entity as defined by MIME (RFC2045, Section 2.4).

MimePart extends the Part interface to add additional RFC822 and MIME specific semantics and attributes. It provides the base interface for the MimeMessage and MimeBodyPart classes


A note on RFC822 and MIME headers

RFC822 and MIME header fields must contain only US-ASCII characters. If a header contains non US-ASCII characters, it must be encoded as per the rules in RFC 2047. 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.

Method Detail

getHeader

java.lang.String getHeader(java.lang.String name,
                           java.lang.String delimiter)
                           throws MessagingException
Get the values of all header fields available for this header, returned as a single String, with the values separated by the delimiter. If the delimiter is null, only the first value is returned.

Parameters:
name - the name of this header
delimiter - delimiter between fields in returned string
Returns:
the value fields for all headers with this name
Throws:
MessagingException

addHeaderLine

void addHeaderLine(java.lang.String line)
                   throws MessagingException
Add a raw RFC822 header-line.

Throws:
IllegalWriteException - if the underlying implementation does not support modification
IllegalStateException - if this Part is obtained from a READ_ONLY folder
MessagingException

getAllHeaderLines

java.util.Enumeration getAllHeaderLines()
                                        throws MessagingException
Get all header lines as an Enumeration of Strings. A Header line is a raw RFC822 header-line, containing both the "name" and "value" field.

Throws:
MessagingException

getMatchingHeaderLines

java.util.Enumeration getMatchingHeaderLines(java.lang.String[] names)
                                             throws MessagingException
Get matching header lines as an Enumeration of Strings. A Header line is a raw RFC822 header-line, containing both the "name" and "value" field.

Throws:
MessagingException

getNonMatchingHeaderLines

java.util.Enumeration getNonMatchingHeaderLines(java.lang.String[] names)
                                                throws MessagingException
Get non-matching header lines as an Enumeration of Strings. A Header line is a raw RFC822 header-line, containing both the "name" and "value" field.

Throws:
MessagingException

getEncoding

java.lang.String getEncoding()
                             throws MessagingException
Get the transfer encoding of this part.

Returns:
content-transfer-encoding
Throws:
MessagingException

getContentID

java.lang.String getContentID()
                              throws MessagingException
Get the Content-ID of this part. Returns null if none present.

setText

void setText(java.lang.String text)
             throws MessagingException
Convenience method that sets the given String as this part's content, with a MIME type of "text/plain". If the string contains non US-ASCII characters. it will be encoded using the platform's default charset. The charset is also used to set the "charset" parameter.

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 Part
Parameters:
text - the text content to set
Throws:
MessagingException - if an error occurs

setText(String text, String charset)

setText

void setText(java.lang.String text,
             java.lang.String charset)
             throws MessagingException
Convenience method that sets the given String as this part's content, with a MIME type of "text/plain" and the specified charset. The given Unicode string will be charset-encoded using the specified charset. The charset is also used to set "charset" parameter.

Parameters:
text - the text content to set
charset - the charset to use for the text
Throws:
MessagingException - if an error occurs

setText

void setText(java.lang.String text,
             java.lang.String charset,
             java.lang.String subtype)
