aoqi@0 46 * The MimeMultipart class is an implementation of the abstract Multipart
aoqi@0 47 * class that uses MIME conventions for the multipart data. <p>
aoqi@0 48 *
aoqi@0 49 * A MimeMultipart is obtained from a MimePart whose primary type
aoqi@0 50 * is "multipart" (by invoking the part's <code>getContent()</code> method)
aoqi@0 51 * or it can be created by a client as part of creating a new MimeMessage. <p>
aoqi@0 52 *
aoqi@0 53 * The default multipart subtype is "mixed". The other multipart
aoqi@0 54 * subtypes, such as "alternative", "related", and so on, can be
aoqi@0 55 * implemented as subclasses of MimeMultipart with additional methods
aoqi@0 56 * to implement the additional semantics of that type of multipart
aoqi@0 57 * content. The intent is that service providers, mail JavaBean writers
aoqi@0 58 * and mail clients will write many such subclasses and their Command
aoqi@0 59 * Beans, and will install them into the JavaBeans Activation
aoqi@0 60 * Framework, so that any JavaMail implementation and its clients can
aoqi@0 61 * transparently find and use these classes. Thus, a MIME multipart
aoqi@0 62 * handler is treated just like any other type handler, thereby
aoqi@0 63 * decoupling the process of providing multipart handlers from the
aoqi@0 64 * JavaMail API. Lacking these additional MimeMultipart subclasses,
aoqi@0 65 * all subtypes of MIME multipart data appear as MimeMultipart objects. <p>
aoqi@0 66 *
aoqi@0 67 * An application can directly construct a MIME multipart object of any
aoqi@0 68 * subtype by using the <code>MimeMultipart(String subtype)</code>
aoqi@0 69 * constructor. For example, to create a "multipart/alternative" object,
aoqi@0 70 * use <code>new MimeMultipart("alternative")</code>.
