| * be configured as a service parameter (see {@link BaseConstants#WRAPPER_PARAM}). |
| * It defaults to {@link BaseConstants#DEFAULT_TEXT_WRAPPER}. |
| * If the content is provided as an {@link InputStream} and the content type specifies a |
| * <tt>charset</tt> parameter (e.g. <tt>text/plain; charset=ISO-8859-15</tt>), |
| * this information is used to decode the text. |
| * If the content is provided as an {@link InputStream} but no <tt>charset</tt> parameter |
| * is specified on the content type, the default charset encoding specified by |
| * {@link MessageContext#DEFAULT_CHAR_SET_ENCODING} is used. |
