class viewflow.This

Helper for building forward referenced flow task.

The rationale is ability to specify references to the class attributes and methods before they are declared.

this is like a self but for the class body.

The references are resolved by the metaclass at the end of the flow construction.

Example:

class MyFlow(Flow):
    start = (
        flow.StartFunction(this.start_flow)
        .Next(this.task)
    )

    task = (
        flow.View(MyView)
        .Assign(this.start.owner)
        .Next(this.end)
    )

    end = flow.End()

    def start_flow(self, activation):
        activation.prepare()
        activation.done()

class viewflow.ThisObject(name)

Helper for forward references on flow tasks.
