Given a non-null ResourceSet representing the available resources at this moment in time return either a ResourceSet that is a subset of the available resources in which the task can run, or None if the task cannot run in the available resources.

Get the list of tasks to execute.
For UnitTask and any class that extends it, if the task wishes to be directly executed, the list should be of size one, and equal to itself. If no resources have been specified, both memory and cores default to the given resources.

Finalize anything after the task has been run.
Finalize anything after the task has been run.
This method should be called after a task has been run. The intended use of this method is to allow for any modification of this task prior to any dependent tasks being run. This would allow any parameters that were passed to dependent tasks as call-by-name to be finalized here. For example, we could have passed an Option[String] that is None until make it Some(String) in this method. Then when the dependent task's getTasks method is called, it can call 'get' on the option and get something.
