Small API Tweak to Task (Worker)

[Sven Reimers]

Hi,

I am trying to build a UI representation of a Task (using a ProgressBar and
other things).

Since Tasks are cancellabe I thought about adding a button to cancel the
underlying Task. So far so good.

Is there any reason why a Task can not express, if it is intended for the
task to act cooperative to a call to cancel? Something along the following
lines

public boolean isCancellable() { return true; }  // default

This would enable users of the API to distinguish between Tasks which
really can be cancelled from those which just fulfill the API contract.

Comments?

-Sven
