'''Actor Oriented Design Patterns''' are software patterns that utilize the Actor Model (for example [[Actor Framework]]). Actors are a powerful tool when creating large, highly parallelized, scalable systems in LabVIEW.

			''Transition from thinking in dataflow to thinking in message flow.'' In larger applications with parallel modules in multiple threads, dataflow is insufficient to describe the interaction. Instead, think of the flow of the messages (methods plus data) exchanged between those modules. Dataflow makes sense for single processes with shorter lifetimes inside self-contained components. In large complex applications, the messaging may be such that a dedicated message broker would be needed. Dataflow will still govern the self-contained code pieces inside the components.<ref>"NI Architect Summit: Object Oriented Programming In LabVIEW" by Nate Chandler-Smith.

			The [[Actor Framework]] is a powerful tool there are many aspects to how it can be implemented. Below are three Actor Oriented Design Patterns implemented with the [[Actor Framework]]. These resemble their non Object-Oriented counterparts, see [[Design Patterns Overview\|Design Patterns]], where these are an implementation of a single actor. There real power lies in multiple Actors working together. These patterns are:

	# Queued State Machine Actor		# Queued State Machine Actor
	# Queued Message Handler Actor		# Queued Message Handler Actor

It sends the first Message on Pre Launch Init Method. Each subsequent Message sends the next Message in the state.

	Because it doesn't override the Actor Core the pattern does not have a UI of its own. It could be paired with another Actor that implements the UI and sends Messages to it to update UI elements. The paired Actor would follow one of the other patterns. See more about the [[State Machine Actor\|State Machine Actor (SMA) Design Pattern]].
