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.

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

  - setText
```
void setText(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
