'''Implicit invocation''' is a term used by some authors for a style of [[software architecture]] in which a system is structured around [[event handling]], using a form of [[Callback (computer science)|callback]]. It is closely related to [[inversion of control]] and what is known informally as the [[Hollywood principle]].<br />
<br />
{{quote|text=The idea behind implicit invocation is that instead of invoking a procedure directly, a component can announce (or broadcast) one or more events. Other components in the system can register an interest in an event by associating a procedure with the event. When the event is announced the system itself invokes all of the procedures that have been registered for the event. Thus an event announcement ''implicitly'' causes the invocation of procedures in other modules.|author=David Garlan and Mary Shaw|source="An Introduction to Software Architecture"<ref>{{Cite book |last=Garlan |first=David |url=https://www.cs.cmu.edu/afs/cs/project/able/ftp/intro_softarch/intro_softarch.pdf |title=An Introduction to Software Architecture |last2=Shaw |first2=Mary |year=1994}}</ref>}}<br />

Implicit invocation is the core technique behind the [[observer pattern]].{{cn|date=November 2019}}<br />
