| * RawRequestParameterModule accesses request parameters without |
| * decoding to the specified <code>form-encoding</code> or casting. It uses the |
| * {@link org.apache.cocoon.environment.Request#get} method instead of the |
| * {@link org.apache.cocoon.environment.Request#getParameter} method of the |
| * {@link org.apache.cocoon.environment.Request Request} This is useful for example |
| * in conjunction with uploads. |
| * |
| * <p>If <code>get()</code> returns a Vector, <code>getAttribute()</code> will return |
| * the first element, otherwise it will return the same as <code>get()</code>. |
| * <code>getAttributeValues()</code> will either convert the Vector to an array, |
| * place the result in a new array, or return the array as is.</p> |
