Examples of javax.json.JsonReader.readObject()

javax.json.JsonReader.readObject()
Returns a JSON object that is represented in the input source. This method needs to be called only once for a reader instance. @return a Json object @throws JsonException if a JSON object cannotbe created due to i/o error (IOException would be cause of JsonException) @throws JsonParsingException if a JSON object cannotbe created due to incorrect representation @throws IllegalStateException if this method, readObject, readArray orclose method is already called
