Member Function Documentation

bool softwarecontainer::JobAbstract::isSuccess ( )

inherited

Helper about return value of jobs.

Describes whether the exit status of a command or a function indicates success or not

Note that this method will interpret exit status only for the last job

Definition at line 85 of file jobabstract.cpp.

{
    if (0 == m_exitStatus) {
        return true;
    }

    return false;
}

bool softwarecontainer::JobAbstract::isError ( )

inherited

Helper about return value of jobs.

Describes whether the exit status of a command or a function indicates error or not

Note that this method will interpret exit status only for the last job

Definition at line 94 of file jobabstract.cpp.

{
    return !isSuccess();
}

bool softwarecontainer::JobAbstract::isRunning ( )

inherited

That method always returns true as soon as the start() method has been called, even if the command fails to start, since we don't know if the exec() occurring after the fork into the container actually succeeds...

Definition at line 103 of file jobabstract.cpp.

{
    // TODO : find a way to test whether the exec() which occurs in the container succeeded
    return (m_pid != 0);
}
