Module: LogicalConstruct::SatisfiableManager

Included in:
Manifest, ResolvingTask
Defined in:
lib/logical-construct/resolving-task.rb

Overview

Ensures that all it's deps are satisfied before proceeding - the action for ResolvingTasks is all about satisfying deps.

Key is how Rake invokes tasks: Task runner calls Task#invoke Which is "setup args" and #invoke_with_call_chain which is return if @already_invoked and #invoke_prerequisites which is prereqs.each{|pr| pr.invoke_with_call_chain } and #execute if needed

So, of note: you'll only get invoked once, ever You'll only be executed if #needed? Deps will get invoked (ish) even if not #needed?
