The set of registered * providers is leveraged, in that the content type for a body part of such a * message reuses the same MessageBodyReader/MessageBodyWriter implementations * as would be used for that content type as a standalone entity.</p> * * <p>For more information on the syntax and semantics of MIME multipart streams, * see the following RFCs:</p> * <ul> * <li><a href="http://www.ietf.org/rfc/rfc2045.txt">Multipurpose Internet Mail * Extensions (MIME) Part One: Format of Internet Message Bodies</a> * (RFC 2045)</li> * <li><a href="http://www.ietf.org/rfc/rfc2046.txt">Multipurpose Internet Mail * Extensions (MIME) Part Two: Media Types</a> (RFC 2046)</li> * <li><a href="http://www.ietf.org/rfc/rfc2047.txt">Multipurpose Internet Mail * Extensions (MIME) Part Three: Message Header Extensions for Non-ASCII * Text</a> (RFC 2047)</li> * <li><a href="http://www.ietf.org/rfc/rfc2048.txt">Multipurpose Internet Mail * Extensions (MIME) Part Four: Registration Procedures</a> (RFC 2048)</li> * <li><a href="http://www.ietf.org/rfc/rfc2048.txt">Multipurpose Internet Mail * Extensions (MIME) Part Five: Conformance Criteria and Examples</a> * (RFC 2049)</li> * </ul> * * <h4>Implementation Notes</h4> * * <p>The following notes describe significant aspects of the implementation * of the MIME MultiPart APIs in this (and related) packages:</p> * <ul> * <li>Although packaged as a Jersey extension, the runtime code in this * library should be portable to any compliant JAX-RS implementation. * Jersey is only required for execution of the unit tests.</li> * </ul> * * <h4>Supported MIME Multipart Capabilities</h4> * * <p>The following list of general MIME MultiPart features is currently * supported:</p> * <ul> * <li>The <code>MIME-Version: 1.0</code> HTTP header is included on generated * responses. It is accepted, but not required, on processed requests.</li> * <li>A <code>MessageBodyReader</code> implementation for consuming MIME * MultiPart entities. See below for usage restrictions.</li> * <li>A <code>MessageBodyWriter</code> implementation for producing MIME * MultiPart entities. The appropriate <code>Provider</code> is used to * serialize each body part, based on its media type.</li> * <li>Optional creation of an appropriate <code>boundary</code> parameter on a * generated <code>Content-Type</code> header, if not already present.</li> * <li>Top level content type of <code>multipart</code>, with the following * supported subtypes: <code>alternative</code>, <code>digest</code>, * <code>mixed</code>, and <code>parallel</code>.</li> * </ul> * * <p>At present, the <code>MessageBodyReader</code> implementation exhibits a * usability issue. It is not currently possible to know ahead of time what * Java class the application would prefer to use for each individual body part, * so an appropriate <code>Provider</code> cannot be selected. Currently, the * unparsed content of each body part is returned (as a byte array) in the * <code>entity</code> property of the returned <code>BodyPart}</code> instance, and * the application can decide what further steps are needed based on the * headers included in that body part. The simplest technique is to examine * the received <code>BodyPart</code>, and then call the <code>getEntityAs()</code> * method once you know which implementation class you would prefer.</p> * * <h4>Not (Yet) Supported MIME Multipart Capabilities</h4> * * <p>The following list of general MIME MultiPart features is NOT (yet, in * most cases) supported:</p> * <ul> * <li>The <code>charset</code> parameter on the <code>Content-Type</code> header * field. Currently, the hard coded charset is FIXME. [RFC2045#5.2]</li> * <li>The <code>Content-Transfer-Encoding</code> header field. [RFC2045#6]</li> * <li>The <code>message/*</code> family of content types.</li> * </ul> */ package org.glassfish.jersey.media.multipart;
