Class MimeBodyPart

    java.lang.Object
      javax.mail.BodyPart
          javax.mail.internet.MimeBodyPart

All Implemented Interfaces:
  MimePart, Part

Direct Known Subclasses:
  PreencodedMimeBodyPart

    public class MimeBodyPart

extends BodyPart
implements MimePart

This class represents a MIME body part. It implements the `BodyPart` abstract class and the `MimePart` interface. MimeBodyParts are contained in `MimeMultipart` objects.

MimeBodyPart uses the `InternetHeaders` class to parse and store the headers of that body part.

A note on RFC 822 and MIME headers

RFC 822 header fields must contain only US-ASCII characters. MIME allows non ASCII characters to be present in certain portions of certain headers, by encoding those characters. RFC 2047 specifies the rules for doing this. 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.

  The DataHandler object representing this Part's content.

### content

    protected byte[] content

  Byte array that holds the bytes of the content of this Part.

### contentStream

    protected java.io.InputStream contentStream

  If the data for this body part was supplied by an InputStream that implements the SharedInputStream interface, `contentStream` is another such stream representing the content of this body part. In this case, `content` will be null.

    JavaMail 1.2

### headers

    protected InternetHeaders headers

  The InternetHeaders object that stores all the headers of this body part.

Constructor Detail

### MimeBodyPart

    public MimeBodyPart()

  An empty MimeBodyPart object is created. This body part maybe filled in by a client constructing a multipart message.

### MimeBodyPart

    public MimeBodyPart(java.io.InputStream is)
                 throws MessagingException

  Constructs a MimeBodyPart by reading and parsing the data from the specified input stream. The parser consumes data till the end of the given input stream. The input stream must start at the beginning of a valid MIME body part and must terminate at the end of that body part.

  Note that the "boundary" string that delimits body parts must not be included in the input stream. The intention is that the MimeMultipart parser will extract each body part's bytes from a multipart stream and feed them into this constructor, without the delimiter strings.

  Parameters:
    `is` - the body part Input Stream
  Throws:
    `MessagingException`

### MimeBodyPart

    public MimeBodyPart(InternetHeaders headers,
                        byte[] content)
                 throws MessagingException

  Constructs a MimeBodyPart using the given header and content bytes.

  Used by providers.

  Parameters:
    `headers` - The header of this part
    `content` - bytes representing the body of this part.
  Throws:
    `MessagingException`

Method Detail

### getSize

    public int getSize()
                throws MessagingException

  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`
  Returns:
    size in bytes, or -1 if not known
  Throws:
    `MessagingException`

### getLineCount

    public int getLineCount()
                     throws MessagingException

  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`
  Returns:
    number of lines, or -1 if not known
  Throws:
    `MessagingException`

### getContentType

### isMimeType

    public boolean isMimeType(java.lang.String mimeType)
                       throws MessagingException

  Is this Part of the specified MIME type? This method compares only the `primaryType` and `subType`. The parameters of the content types are ignored.

  For example, this method will return `true` when comparing a Part of content type "text/plain" with "text/plain; charset=foobar".

  If the `subType` of `mimeType` is the special character '*', then the subtype is ignored during the comparison.

  Specified by:
    `isMimeType` in interface `Part`
  Throws:
    `MessagingException`

    public java.lang.String getDescription()
                                    throws MessagingException

  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`
  Returns:
    content description
  Throws:
    `MessagingException`

### setDescription

    public void setDescription(java.lang.String description)
                        throws MessagingException

  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 platform's default 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.

  Specified by:
    `setDescription` in interface `Part`
  Parameters:
    `description` - content description
  Throws:
    `IllegalWriteException` - if the underlying implementation does not support modification
    `java.lang.IllegalStateException` - if this body part is obtained from a READ_ONLY folder.
    `MessagingException` - otherwise; an UnsupportedEncodingException may be included in the exception chain if the charset conversion fails.

### setDescription

    public void setDescription(java.lang.String description,
                               java.lang.String charset)
                        throws MessagingException

  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.

  Parameters:
    `description` - Description
    `charset` - Charset for encoding
  Throws:
    `IllegalWriteException` - if the underlying implementation does not support modification
    `java.lang.IllegalStateException` - if this body part is obtained from a READ_ONLY folder.
    `MessagingException` - otherwise; an UnsupportedEncodingException may be included in the exception chain if the charset conversion fails.

### getFileName

    public java.lang.String getFileName()
                                 throws MessagingException

  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.encodefilename` 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`
  Returns:
    filename
  Throws:
    `MessagingException`

### setFileName

    public void setFileName(java.lang.String filename)
                     throws MessagingException

  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`
  Parameters:
    `filename` - Filename to associate with this part
  Throws:
    `IllegalWriteException` - if the underlying implementation does not support modification
    `java.lang.IllegalStateException` - if this body part is obtained from a READ_ONLY folder.
    `MessagingException`

### getInputStream

    public java.io.InputStream getInputStream()
                                       throws java.io.IOException,
                                              MessagingException

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

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

  Specified by:
    `getInputStream` in interface `Part`
  Returns:
    an InputStream
  Throws:
    `MessagingException`
    `java.io.IOException` - this is typically thrown by the DataHandler. Refer to the documentation for javax.activation.DataHandler for more details.
  See Also:
    `getContentStream()`, `DataHandler.getInputStream()`

### getContentStream

    protected java.io.InputStream getContentStream()
                                            throws MessagingException

  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.

  Throws:
    `MessagingException`
  See Also:
    `content`, `MimeMessage.getContentStream()`

### getRawInputStream

    public java.io.InputStream getRawInputStream()
                                          throws MessagingException

  Return an InputStream to the raw data with any Content-Transfer-Encoding intact. This method is useful if the "Content-Transfer-Encoding" header is incorrect or corrupt, which would prevent the `getInputStream` method or `getContent` method from returning the correct data. In such a case the application may use this method and attempt to decode the raw data itself.

  This implementation simply calls the `getContentStream` method.

  Throws:
    `MessagingException`
  Since:
    JavaMail 1.2
  See Also:
    `getInputStream()`, `getContentStream()`

### getDataHandler

    public javax.activation.DataHandler getDataHandler()
                                                throws MessagingException

  Return a DataHandler for this body part's content.

  The implementation provided here works just like the the implementation in MimeMessage.

  Specified by:
    `getDataHandler` in interface `Part`
  Returns:
    DataHandler for the content
  Throws:
    `MessagingException`
  See Also:
    `MimeMessage.getDataHandler()`

### getContent

    public java.lang.Object getContent()
                                throws java.io.IOException,
                                       MessagingException

  Return the content as a java object. The type of the object returned is of course dependent on the content itself. For example, the native format of a text/plain content is usually a String object. The native format for a "multipart" content is always a Multipart subclass. For content types that are unknown to the DataHandler system, an input stream is returned as the content.

  This implementation obtains the content from the DataHandler. That is, it invokes getDataHandler().getContent(); If the content is a Multipart or Message object and was created by parsing a stream, the object is cached and returned in subsequent calls so that modifications to the content will not be lost.

  Specified by:
    `getContent` in interface `Part`
  Returns:
    Object
  Throws:
    `MessagingException`
    `java.io.IOException` - this is typically thrown by the DataHandler. Refer to the documentation for javax.activation.DataHandler for more details.
  See Also:
    `DataHandler.getContent()`

### setDataHandler

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

  This method provides the mechanism to set this body part's content. The given DataHandler object should wrap the actual content.

  Specified by:
    `setDataHandler` in interface `Part`
  Parameters:
    `dh` - The DataHandler for the content
  Throws:
    `IllegalWriteException` - if the underlying implementation does not support modification
    `java.lang.IllegalStateException` - if this body part is obtained from a READ_ONLY folder.
    `MessagingException`

### setContent

    public void setContent(java.lang.Object o,
                           java.lang.String type)
                    throws MessagingException

  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.

  Specified by:
    `setContent` in interface `Part`
  Parameters:
    `o` - the content object
    `type` - Mime type of the object
  Throws:
    `IllegalWriteException` - if the underlying implementation does not support modification of existing values
    `java.lang.IllegalStateException` - if this body part is obtained from a READ_ONLY folder.
    `MessagingException`

### setText

    public 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 `MimePart`
  Specified by:

### updateHeaders

    protected void updateHeaders()
                          throws MessagingException

  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.

  Throws:
    `MessagingException`
