Package TEES :: Package Tools :: Module ProcessUtils :: Class ProcessWrapper

Class ProcessWrapper

Killing a process spawned by a shell is not really possible (at least in Python). This becomes a problem, if a tool requires multiple (e.g. piped) processes to be ran. With ProcessWrapper, all processes can be called directly from Python so that their ids are known and they can be killed if they hang. A ProcessWrapper can be passed as a parameter to ProcessUtils functions in place of a subprocess.Popen object.
