TaskQueue

============ This module is designed to store system commands for later use. The module contains the following classes:

Task

A Task object represents an OS command which has the following members:

• GUID A unique identifier
• description A description of the Task
• command An executable command line task eg. echo
• execute() A method to run the stored command

CAUTION: execute() will run unsanitized input

TaskQueue

A FIFO list of Task objects. This will allow us to store commands for later execution. A TaskQueue has the following members:

• push(Task) Pushes a Task to the end of the queue
• pop() Removes and returns the next Task
• peek_all() Looks at all of the Tasks in the queue
• peek_next() Looks at the next Task in the queue
• count() Returns the number of Tasks left in the queue
• is_empty() Tells us if there is any more Tasks left in the queue

##Example

>>> from taskQueue import Task
>>> from taskQueue import TaskQueue
>>> t1 = Task(description="Hello World", command="echo Hello World")
>>> t2 = Task(description="list directory", command="ls")
>>> queue = TaskQueue()
>>> queue.push(t2)
>>> queue.push(t1)
>>> t = queue.pop()
>>> print ("Running task %s\n" % t.GUID)
Running task bb05e165-84ec-4eee-8065-799320223197
>>> t.execute()
Hello World
>>> t = queue.pop()
>>> t.execute()
