Package roshlaunch :: Module pmon :: Class Process

Class Process

object --+
         |
        Process

Basic process representation for ProcessMonitor. Must be subclassed to provide actual start()/stop() implementations.

Constructor *must* be called from the Python Main thread in order for signal handlers to register properly.
