Detailed Description

Abstract base class for DSPatch components.

Classes derived from Component can be added to a Circuit and routed to and from other Components.

On construction, derived classes must configure the component's IO buses by calling SetInputCount_() and SetOutputCount_() respectively.

Derived classes must also implement the virtual method: Process_(). The Process_() method is a callback from the DSPatch engine that occurs when a new set of input signals is ready for processing. The Process_() method has 2 arguments: the input bus, and the output bus. This method's purpose is to pull its required inputs out of the input bus, process these inputs, and populate the output bus with the results (see SignalBus).

In order for a component to do any work it must be ticked. This is performed by repeatedly calling the Tick() method. This method is responsible for acquiring the next set of input signals from its input wires and populating the component's input bus. The acquired input bus is then passed to the Process_() method.

PERFORMANCE TIP: If a component is capable of processing its buffers out-of-order within a stream processing circuit, consider initialising its base with ProcessOrder::OutOfOrder to improve performance. Note however that Process_() must be thread-safe to operate in this mode.
