Class
    Foam::zoneToPoint
 
Description
    A \c topoSetPointSource to convert \c pointZone(s) to a \c pointSet.
 
    Operands:
    \table
      Operand   | Type         | Location
      input     | pointZone(s) | $FOAM_CASE/constant/polyMesh/pointZones
      output    | pointSet     | $FOAM_CASE/constant/polyMesh/sets/<set>
    \endtable
 
Usage
    Minimal example by using \c system/topoSetDict.actions:
    \verbatim
    {
        // Mandatory (inherited) entries
        name        <name>;
        type        pointSet;
        action      <action>;
 
        // Mandatory entries
        source      zoneToPoint;
 
        // Conditional mandatory entries
        // Select either of the below
 
        // Option-1
        zones
        (
            <pointZoneName0>
            <pointZoneName1>
            ...
        );
 
        // Option-2
        zone     <pointZoneName>;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                           | Type | Req'd | Dflt
      name       | Name of pointSet                      | word |  yes  | -
      type       | Type name: pointSet                   | word |  yes  | -
      action     | Action applied on points - see below  | word |  yes  | -
      source     | Source name: zoneToPoint              | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new pointSet from selected points
      add      | Add selected points into this pointSet
      subtract | Remove selected points from this pointSet
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description                | Type     | Req'd  | Dflt
      zones    | Names of input pointZones  | wordRes  | cond'l | -
      zone     | Name of input pointZone    | wordRe   | cond'l | -
    \endverbatim
 
Note
    The order of precedence among the conditional mandatory entries from the
    highest to the lowest is \c zones, and \c zone.
