| /** |
| * A single attachment to a {@code SOAPMessage} object. A |
| * {@code SOAPMessage} object may contain zero, one, or many |
| * {@code AttachmentPart} objects. Each {@code |
| * AttachmentPart} object consists of two parts, |
| * application-specific content and associated MIME headers. The |
| * MIME headers consists of name/value pairs that can be used to |
| * identify and describe the content.<p> |
| * |
| * An {@code AttachmentPart} object must conform to |
| * certain standards. |
| * |
| * <OL> |
| * <LI>It must conform to <A href= |
| * "http://www.ietf.org/rfc/rfc2045.txt">MIME [RFC2045] |
| * standards</A></LI> |
| * |
| * <LI>It MUST contain content</LI> |
| * |
| * <LI> |
| * The header portion MUST include the following header: |
| * |
| * <UL> |
| * <LI> |
| * {@code Content-Type}<BR> |
| * This header identifies the type of data in the content |
| * of an {@code AttachmentPart} object and MUST |
| * conform to [RFC2045]. The following is an example of a |
| * Content-Type header: |
| * <PRE> |
| * Content-Type: application/xml |
| * |
| * </PRE> |
| * The following line of code, in which {@code ap} is |
| * an {@code AttachmentPart} object, sets the header |
| * shown in the previous example. |
| * <PRE>{@code |
| * ap.setMimeHeader("Content-Type", "application/xml"); |
| * }</PRE> |
| * </LI> |
| * </UL> |
| * </LI> |
| * </OL> |
| * |
| * <P>There are no restrictions on the content portion of an |
| * {@code AttachmentPart} object. The content may be anything |
| * from a simple plain text object to a complex XML document or |
| * image file.</P> |
| * |
| * <P>An {@code AttachmentPart} object is created with the |
| * method {@code SOAPMessage.createAttachmentPart}. After |
| * setting its MIME headers, the {@code AttachmentPart} |
| * object is added to the message that created it with the method |
| * {@code SOAPMessage.addAttachmentPart}.<P> |
| * |
| * The following code fragment, in which {@code m} is a |
| * {@code SOAPMessage} object and {@code contentStringl} |
| * is a {@code String}, creates an instance of {@code |
| * AttachmentPart}, sets the {@code AttachmentPart} |
| * object with some content and header information, and adds the |
| * {@code AttachmentPart} object to the {@code |
| * SOAPMessage} object. |
| * <PRE> |
| * AttachmentPart ap1 = m.createAttachmentPart(); |
| * ap1.setContent(contentString1, "text/plain"); |
| * m.addAttachmentPart(ap1); |
| * </PRE> |
| * |
| * <P>The following code fragment creates and adds a second {@code |
| * AttachmentPart} instance to the same message. {@code |
| * jpegData} is a binary byte buffer representing the jpeg |
| * file.</P> |
| * <PRE> |
| * AttachmentPart ap2 = m.createAttachmentPart(); |
| * byte[] jpegData = ...; |
| * ap2.setContent(new ByteArrayInputStream(jpegData), "image/jpeg"); |
| * m.addAttachmentPart(ap2); |
| * </PRE> |
| * |
| * <P>The {@code getContent} method retrieves the contents |
| * and header from an {@code AttachmentPart} object. |
| * Depending on the {@code DataContentHandler} objects |
| * present, the returned {@code Object} can either be a typed |
| * Java object corresponding to the MIME type or an {@code |
| * InputStream} object that contains the content as |
| * bytes.</P> |
| * <PRE> |
| * String content1 = ap1.getContent(); |
| * java.io.InputStream content2 = ap2.getContent(); |
| * </PRE> |
| * The method {@code clearContent} removes all the content |
| * from an {@code AttachmentPart} object but does not affect |
| * its header information. |
| * <PRE> |
| * ap1.clearContent(); |
| * </PRE> |
