Usage

Construct your application with a task parallel model

• Application
  • actfw_core.Application : Main application
• Workers
  • actfw_core.task.Producer : Task generator
    • actfw_core.capture.V4LCameraCapture : Generate UVC camera capture image
  • actfw_core.task.Pipe : Task to Task converter
  • actfw_core.task.Consumer : Task terminator

Each worker is executed in parallel.

User should

• Define subclass of Producer/Pipe/Consumer

class MyPipe(actfw_core.task.Pipe):
    def proc(self, i):
        ...

• Connect defined worker objects

p  = MyProducer()
f1 = MyPipe()
f2 = MyPipe()
c  = MyConsumer()
p.connect(f1)
f1.connect(f2)
f2.connect(c)

• Register to Application

app = actfw_core.Application()
app.register_task(p)
app.register_task(f1)
app.register_task(f2)
app.register_task(c)

• Execute application

app.run()
