Implementations of this interface support the conduct of "operations": exchanges between two distinct ends of an arbitrary number of data payloads and metadata such as a name for the operation, initial and terminal metadata in each direction, and flow control. These operations may be used for transfers of data, remote procedure calls, status indication, or anything else applications choose. éNcs eZdZdZ‡fdd„Z‡ZS)ÚNoSuchMethodErrorauIndicates that an unrecognized operation has been called.
