|
45 * The MimeMultipart class is an implementation of the abstract Multipart |
|
46 * class that uses MIME conventions for the multipart data. <p> |
|
47 * |
|
48 * A MimeMultipart is obtained from a MimePart whose primary type |
|
49 * is "multipart" (by invoking the part's <code>getContent()</code> method) |
|
50 * or it can be created by a client as part of creating a new MimeMessage. <p> |
|
51 * |
|
52 * The default multipart subtype is "mixed". The other multipart |
|
53 * subtypes, such as "alternative", "related", and so on, can be |
|
54 * implemented as subclasses of MimeMultipart with additional methods |
|
55 * to implement the additional semantics of that type of multipart |
|
56 * content. The intent is that service providers, mail JavaBean writers |
|
57 * and mail clients will write many such subclasses and their Command |
|
58 * Beans, and will install them into the JavaBeans Activation |
|
59 * Framework, so that any JavaMail implementation and its clients can |
|
60 * transparently find and use these classes. Thus, a MIME multipart |
|
61 * handler is treated just like any other type handler, thereby |
|
62 * decoupling the process of providing multipart handlers from the |
|
63 * JavaMail API. Lacking these additional MimeMultipart subclasses, |
|
64 * all subtypes of MIME multipart data appear as MimeMultipart objects. <p> |
|
65 * |
|
66 * An application can directly construct a MIME multipart object of any |
|
67 * subtype by using the <code>MimeMultipart(String subtype)</code> |
|
68 * constructor. For example, to create a "multipart/alternative" object, |
|
69 * use <code>new MimeMultipart("alternative")</code>. |
