Dynamic Invocation Interface
Encyclopedia
The Dynamic Invocation Interface (DII) is an API which allows dynamic construction of CORBA
object
invocations. It is used at compile
time when a client
does not have knowledge about the object it wants to invoke. With this interface an argument list is marshalled, a function is named, and a request for service is sent to the object server. DII will usually have an asynchronous mode of operation.
The following types of applications would require or benefit from DII: browsers for CORBA services, application browsers, bridges (protocol converters), applications accessing huge numbers of different interfaces, monitoring applications.
DII also provides a deferred synchronous invocation. Deferred synchronous invocations are submitted without having to wait for a response. This is similar to a one-way operation except return values and out parameters are possible, but must be polled

Polling (computer science)
Polling, or polled operation, in computer science, refers to actively sampling the status of an external device by a client program as a synchronous activity. Polling is most often used in terms of input/output , and is also referred to as polled or software driven .Polling is sometimes used...
