Class
    Foam::functionObjects::stopAtFile
 
Description
    Stops the run when the specified file is created in the case directory
    and optionally write results before stopping.
 
    The default name of the trigger file is \c $FOAM_CASE/<name> where \c
    <name> is the name of the functionObject entry.
 
    Currently the following action types are supported:
    - noWriteNow
    - writeNow
    - nextWrite (default)
 
    Examples of function object specification:
    \verbatim
    stop
    {
        type            stopAtFile;
 
        libs            ("libutilityFunctionObjects.so");
    }
    \endverbatim
    will stop the run at the next write after the file "stop" is created in the
    case directory.
 
    \verbatim
    stop
    {
        type    stopAtFile;
        libs    ("libutilityFunctionObjects.so");
        file    "$FOAM_CASE/stop";
        action  writeNow;
    }
    \endverbatim
    will write the fields and stop the run when the file "stop" is created in
    the case directory.
 
Usage
    \table
        Property | Description            | Required | Default value
        type     | type name: stopAtFile  | yes      |
        file     | Trigger file path name | no       | $FOAM_CASE/<name>
        action   | Action executed        | no       | nextWrite
    \endtable
