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