Both Java and C # event handling are implemented by the event source-event responder mechanism, but not exactly the same. Java implementation is an event source and event responder level Two entity object way, the event responder here is also the event listener, and C # is a kind of event source-proxy-event responder L
(CRL) or uses an online certificate status Protocol (OCSP) record. However, the problem with CRLs is that the list items of CRLs are increasing and need to be downloaded continuously.
OCSP is more lightweight because it only gets one record at a time. The side effect, however, is that when you connect to the server, OCSP requests must be sent to a third party responder, which increases latency and the likelihood of failure. In fact, OCSP responders
Uievent is a collection of uitouch that is responsible for responding to touch events in iOS. The concept of a responder chain is also mentioned, in which all events have a first responder, and events can be passed down the responder chain.

Windows is a message-driven operating system, and the programs running on it are running, and as the object-oriented development platform matures, Microsoft encapsulates the message mechanism into an easier-to-understand event model with 3 key points: The owner of the event, the responder of the event, the subscription to the eventTo reduce the amount of coupling and code generated by event subscri
