                                            throws ODataException

This method gets the metadata from cache if getMetadataCache boolean is set to true. If getMetadataCache is set to false, then it gets fresh metadata even if the metadata is available in cache. For both cases,the headers have to be passed. This method internally updates the cache if metadata is requested from cache and is not available. The updating of the cache is thread safe. If one thread is accessing the cache, the other thread fails with error stating "Metadata currently being loaded. Please try again later".
