      • getEntity

        public Object getEntity()
        Returns the entity object to be unmarshalled from a request, or to be marshalled on a response.
        Returns:
        an entity of this body part.
        Throws:
        IllegalStateException - if this method is called on a MultiPart instance; access the underlying BodyParts instead

      • setEntity

        public void setEntity​(Object entity)
        Set the entity object to be unmarshalled from a request, or to be marshalled on a response.
        Parameters:
        entity - the new entity object.
        Throws:
        IllegalStateException - if this method is called on a MultiPart instance; access the underlying BodyParts instead

      • getHeaders

        public MultivaluedMap<String,​String> getHeaders()
        Returns a mutable map of HTTP header value(s) for this BodyPart, keyed by the header name. Key comparisons in the returned map must be case-insensitive.

        Note: MIME specifications says only headers that match Content-* should be included on a BodyPart.

        Returns:
        mutable map of HTTP header values.

      • getParameterizedHeaders

        public MultivaluedMap<String,​ParameterizedHeader> getParameterizedHeaders()
                                                                         throws ParseException
        Returns an immutable map of parameterized HTTP header value(s) for this BodyPart, keyed by header name. Key comparisons in the returned map must be case-insensitive. If you wish to modify the headers map for this BodyPart, modify the map returned by getHeaders() instead.
        Returns:
        immutable map of HTTP header values.
        Throws:
        ParseException - if an un-expected/in-correct value is found during parsing the headers.

      • getContentDisposition

        Sets the content disposition.
        Parameters:
        contentDisposition - the content disposition.

      • getMediaType

        public MediaType getMediaType()
        Returns the MediaType for this BodyPart. If not set, the default MediaType MUST be text/plain.

        media type for this body part.

      • getParent

        public MultiPart getParent()
        Returns the parent MultiPart (if any) for this BodyPart.
        Returns:

      • getEntityAs

        public <T> T getEntityAs​(Class<T> clazz)

        Returns:
        entity after appropriate conversion to the requested type.
