# Dataflow chaining is the combination of more than 2 functions.
# This is how the data flows in this example code:
getWebcamImage -> addFilters -> showOnScreen

# This class symbolizes our image data which is a simple integer in this case
WebcamImage
    init
        my.data = rand(-100, 100)

    get
        data
            return my.data

    set
        data newData
            my.data = newData

# Capture one frame
getWebcamImage
    return WebcamImage()

# Process image
addFilters image
    source = image.data
    image.data = source + rand(-100, 100)
    return image

# Show it on the screen
showOnScreen image
    print image.data

# Theoretically you can create a main loop now.
# To demonstrate the data flow I'm just going to do this 10 times:
for i = 1 to 10
    getWebcamImage()
