Subject [GitHub] incubator-brooklyn pull request: Support suspending machines
Date Tue, 21 Jul 2015 16:26:57 GMT
GitHub user sjcorbett opened a pull request:

    Support suspending machines

    Locations can indicate that they can suspend machines by implementing a new `SuspendsMachines`
    A use of this is given in `MachineLifecycleEffectorTasks`, which provides a `suspend`
effector implementation. Attaching this effector to entities is left to subclasses of MLET.
    An interface for locations that can resume machines is also given but unused. I began
an implementation but realised that we need to discuss what it means to "resume" a machine.
Eventually `JcloudsLocation` should implement `SuspendResumeLocation` rather than `SuspendsMachines`.

    And uses them in JcloudsLocation.

    MachineLifecycleEffectorTasks can suspend as well as stop machines.
    Leaves it to subclasses to attach the effector to entities.
