Class
    Foam::functionObjects::runTimePostPro::functionObjectBase
 
Description
    Base class for function object visualisation
 
    Dictionary controls
    \table
        Property     | Description                          | Required | Default
        functionObject | The data source                    | yes |
        clearObjects | Remove file after use                | no  | no
        liveObject   | Prefer simulation data source        | no  | true
    \endtable
 
    The "live" keyword indiates that from within the simulation (in memory)
    is preferred over data from disk (for example).
