Usage

From source file:ca.ualberta.cmput301f13t13.storyhoard.serverClasses.ESUpdates.java

/**
 * Deletes an entry (in this case a story object) specified by the id from
 * the server. You must specify the id as a string (but in the format of
 * a UUID), and the server as a string as well. In addition, output from
 * the server (the response's content) will also be printed out to
 * System.err. </br></br>/*from w  w w.j  a v  a2  s  .com*/
 * 
 * Example call: </br>
 * Let's say the following story is on the server. </br>
 * </br> String id = f1bda3a9-4560-4530-befc-2d58db9419b7; 
 *       Story myStory = new Story(id, "The Cow", "John Wayne", 
 *                            "A story about a Cow", phoneId). 
 * </br> To delete myStory from the server, call </br>
 * String server = "http://cmput301.softwareprocess.es:8080/cmput301f13t13/stories/" </br>
 * String id = f1bda3a9-4560-4530-befc-2d58db9419b7; </br>
 * deleteStory(id, server); </br></br>
 * 
 * @param id
 *          Must be a String in the valid format of a UUID. See example
 *          above for the formatting of a UUID.
 * @param server
 *          The location on elastic search to search for the responses.
 *          It expects this information as a String.</br>
 *          See the above example for an example of a valid server string
 *          format.
