Examples of org.codehaus.jettison.json.JSONObject.optString()

org.codehaus.jettison.json.JSONObject.optString()
Get an optional string associated with a key. It returns an empty string if there is no such key. If the value is not a string and is not null, then it is coverted to a string. @param key A key string. @return A string which is the value.
