Example 16 with Filter

use of org.jdom2.filter.Filter in project mycore by MyCoRe-Org.

the class MCRRestAPIClassifications method showObject.

/**
 *  returns a single classification object
 *
 * @param classID - the classfication id
 * @param format
 *   Possible values are: json | xml (required)
 * @param filter
 * 	 a ';'-separated list of ':'-separated key-value pairs, possible keys are:
 *      - lang - the language of the returned labels, if ommited all labels in all languages will be returned
 *      - root - an id for a category which will be used as root
 *      - nonempty - hide empty categories
 * @param style
 * 	a ';'-separated list of values, possible keys are:
 *   	- 'checkboxtree' - create a json syntax which can be used as input for a dojo checkboxtree;
 *      - 'checked'   - (together with 'checkboxtree') all checkboxed will be checked
 *      - 'jstree' - create a json syntax which can be used as input for a jsTree
 *      - 'opened' - (together with 'jstree') - all nodes will be opened
 *      - 'disabled' - (together with 'jstree') - all nodes will be disabled
 *      - 'selected' - (together with 'jstree') - all nodes will be selected
 * @param request - the HTTPServletRequestObject
 * @param callback - used in JSONP to wrap json result into a Javascript function named by callback parameter
 * @return a Jersey Response object
 * @throws MCRRestAPIException
