```
- Method Detail
  - updateHeaders
```
protected void updateHeaders()
```
    Description copied from class: MimeBodyPart
    
    Examine the content of this body part and update the appropriate MIME headers. Typical headers that get set here are Content-Type and Content-Transfer-Encoding. Headers might need to be updated in two cases:
    - A message being crafted by a mail application will certainly need to activate this method at some point to fill up its internal headers.
    - A message read in from a Store will have obtained all its headers from the store, and so doesn't need this. However, if this message is editable and if any edits have been made to either the content or message structure, we might need to resync our headers.
    In both cases this method is typically called by the Message.saveChanges method.
    
    Overrides:
    
    updateHeaders in class MimeBodyPart
  - getSize
```
public int getSize()
            throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Return the size of the content of this body part 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 class MimeBodyPart
    
    Returns:
    size in bytes, or -1 if not known
    
    Throws:
    
    MessagingException
  - getLineCount
```
public int getLineCount()
                 throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Return the number of lines for the content of this Part. 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:

  - getDescription
```
public String getDescription()
                      throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Returns the "Content-Description" header field of this body part. This typically associates some descriptive information with this part. Returns null if this field is unavailable or its value is absent.
    If the Content-Description field is encoded as per RFC 2047, it is decoded and converted into Unicode. If the decoding or conversion fails, the raw data is returned as is.
    This implementation uses getHeader(name) to obtain the requisite header field.
    
    Specified by:
    
    getDescription in interface Part
    
    Overrides:
    
    getDescription in class MimeBodyPart
    
    Returns:
    content description
    
    Throws:
    
    MessagingException
  - setDescription
```
public void setDescription(String description,
                  String charset)
                    throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Set the "Content-Description" header field for this body part. If the description parameter is null, then any existing "Content-Description" fields are removed.
    If the description contains non US-ASCII characters, it will be encoded using the specified charset. If the description contains only US-ASCII characters, no encoding is done and it is used as is.
    Note that if the charset encoding process fails, a MessagingException is thrown, and an UnsupportedEncodingException is included in the chain of nested exceptions within the MessagingException.
    
    Overrides:
    
    setDescription in class MimeBodyPart
    
    Parameters:
    description - Description
    charset - Charset for encoding
    
    Throws:
    
    IllegalWriteException - if the underlying implementation does not support modification
    
    MessagingException - otherwise; an UnsupportedEncodingException may be included in the exception chain if the charset conversion fails.
  - getFileName
```
public String getFileName()
                   throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Get the filename associated with this body part.
    Returns the value of the "filename" parameter from the "Content-Disposition" header field of this body part. If its not available, returns the value of the "name" parameter from the "Content-Type" header field of this body part. Returns null if both are absent.
    If the mail.mime.decodefilename System property is set to true, the MimeUtility.decodeText method will be used to decode the filename. While such encoding is not supported by the MIME spec, many mailers use this technique to support non-ASCII characters in filenames. The default value of this property is false.
    
    Specified by:
    
    getFileName in interface Part
    
    Overrides:
    
    getFileName in class MimeBodyPart
    
    Returns:
    filename
    
    Throws:
    
    MessagingException
  - setFileName
```
public void setFileName(String filename)
                 throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Set the filename associated with this body part, if possible.
    Sets the "filename" parameter of the "Content-Disposition" header field of this body part. For compatibility with older mailers, the "name" parameter of the "Content-Type" header is also set.
    If the mail.mime.encodefilename System property is set to true, the MimeUtility.encodeText method will be used to encode the filename. While such encoding is not supported by the MIME spec, many mailers use this technique to support non-ASCII characters in filenames. The default value of this property is false.
    
    Specified by:
    
    setFileName in interface Part
    
    Overrides:
    
    setFileName in class MimeBodyPart
    
    Parameters:
    filename - Filename to associate with this part
    
    Throws:
    
    IllegalWriteException - if the underlying implementation does not support modification of this header
    
    MessagingException
  - getContentStream
```
protected InputStream getContentStream()
                                throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    Produce the raw bytes of the content. This method is used when creating a DataHandler object for the content. Subclasses that can provide a separate input stream for just the Part content might want to override this method.
    
    Overrides:
    
    getContentStream in class MimeBodyPart
    
    Throws:
    
    MessagingException

```
public void setContent(Object o,
              String type)
                throws MessagingException
```
    Description copied from class: MimeBodyPart
    
    A convenience method for setting this body part's content.
    The content is wrapped in a DataHandler object. Note that a DataContentHandler class for the specified type should be available to the JavaMail implementation for this to work right. That is, to do setContent(foobar, "application/x-foobar"), a DataContentHandler for "application/x-foobar" should be installed. Refer to the Java Activation Framework for more information.
