InferenceFlow QML Type

Connects inference steps into a runnable pipeline. More...

Detailed Description

InferenceFlow groups a set of InferenceStep steps and wires them into a pipeline. The steps are declared as children of the flow, which is the default property, and are connected to each other through the connections declared on each step. Consecutive steps without explicit connections are chained by matching output and input port types.

When the QML component completes, the flow builds the underlying C++ QInferenceFlow from its steps. Call start() to run the pipeline.

See also InferenceStep, InferenceVideoSource, VisionInference, and InferenceResultParser.

Property Documentation

steps : list<InferenceStep>

This property holds the list of steps that make up the flow.

This is the default property of InferenceFlow, so InferenceStep objects declared as children of a flow are added to this list.

See also InferenceStep.

Method Documentation

void start(Window window)

Starts running the flow.

If window is a valid Qt Quick window, the flow starts on the render thread before the next synchronization stage of window. Otherwise, it starts immediately.

Calling this method has no effect until the component has completed and the underlying flow has been built.
