Instructions
You are developing a content management system for a website that hosts articles, blog posts, and other written content. You have been tasked with implementing a task handler that will process tasks in a priority queue. The task handler will receive tasks and based on the load on the server and their priority will decide which task to execute next. If the server is under heavy load, then the priority number has to be higher for the task to be executed. The server will dynamically change the load based on the load.
1. Initialize TaskHandler
The TaskHandler needs to be initialized with a queue and a default load_level.
Implement the initializer of the class TaskHandler that takes an Array of Strings of the tasks names as an argument and storing it in an instance variable called @tasks.
The initializer should also create the instance variable @task_condition_logic that stores a Proc that takes an Int32 and returns true if the argument is equal to or greater than the 0 and false if it is less than 0.
task_handler = TaskHandler.new(["task1", "task2", "task3"])
# => #<TaskHandler:0x7fd8d4cfbf00 @tasks=["task1", "task2", "task3"], @task_condition_logic=#<Proc(Int32, Bool):0x562536a4a330>>2. Update the task condition logic
The server has to be able to update the task condition logic based on the load of the server.
Implement the method TaskHandler#update_task_condition_logic that takes a block as an argument and the block should be stored in the instance variable @task_condition_logic.
task_handler = TaskHandler.new(["task1", "task2", "task3"])
task_handler.update_task_condition_logic { |load| load > 1 }
# => #<TaskHandler:0x7f068118cf00 @tasks=["task1", "task2", "task3"], @task_condition_logic=#<Proc(Int32, Bool):0x562df99d0370>>3. Execute the next task
The server has to be able to execute the next task in the queue.
The first task in the @tasks array is the next task to be executed.
The task should be executed if the priority level of the task given returns true when passed to the @task_condition_logic proc.
It shall return messages based on if the task was executed or not.
If the task was executed it should return: "Completed <task>".
If the task was not executed it should return: "Could not complete <task>".
If the task was executed it should be removed from the @tasks array.
Implement the method TaskHandler#execute_next_task that takes the priority level as Int32 of the next task as an argument and returns a String based on if the task was executed or not.
task_handler = TaskHandler.new(["task1", "task2", "task3"])
task_handler.update_task_condition_logic { |load| load > 1 }
task_handler.execute_next_task(2)
# => "Completed task1"
task_handler.execute_next_task(1)
# => "Could not complete task2"Task Handler
